Why Does Your Motar 1 Quartz Coil Crack? Causes, Prevention & Maintenance Tips
Have you noticed a crack in your Longmada Motar 1 quartz coil after just one or a few uses? You are not alone. One common concern among quartz atomizer users is why the heating cup may develop cracks even when the device is relatively new.
The Longmada Motar 1 quartz coil is designed for wax atomizers and works best within a recommended power range of 20–25W. However, quartz heating components are sensitive to certain operating conditions, including sudden temperature changes, excessive heat, physical impact, and improper cleaning.
So, why does a Motar 1 coil crack? Does it always mean the coil is defective? And what can you do to help prevent cracks and extend the life of your replacement coil?
In this guide, we will explain the common causes of quartz coil cracking, show you how to use and maintain your Motar 1 coil properly, and help you identify when a replacement or further inspection may be necessary.
Important: If your quartz heating cup develops a visible crack, stop using the coil. Do not continue heating a damaged component or attempt to repair it yourself.
What Is the Longmada Motar 1 Quartz Coil?
The Longmada Motar 1 is a wax atomizer designed with a quartz heating cup. Its replaceable coil design allows users to replace the heating component without purchasing an entirely new device.
The Motar 1 and Motar 2 use compatible replacement cores, while the Motar 3 requires its own dedicated replacement coil.
Here are the key specifications and usage recommendations for the Motar 1 replacement coil:
-
Product type: Replaceable quartz heating coil
-
Recommended power: 20–25W
-
Resistance: Approximately 0.4Ω
-
Connection: 510-thread atomizer system
-
Compatible models: Longmada Motar 1 and Motar 2
-
Main maintenance requirement: Allow the heating cup to cool completely before cleaning or handling it.
The quartz heating cup provides a dedicated surface for heating wax concentrates. Like other rigid heating components, however, quartz can be damaged by thermal stress or physical force.
Understanding these factors is the first step toward preventing premature coil damage.
1. Why Does a Motar 1 Quartz Coil Crack After Only a Few Uses?
There is no single explanation for every cracked quartz coil. The location and appearance of the crack, the power setting, the heating duration, and the cleaning method can all provide useful clues.
Let's examine the most common possibilities.
Reason 1: Sudden Temperature Changes
One of the most important factors to consider is thermal shock.
When quartz is heated, its temperature changes and the material expands. When it cools, it contracts. If different areas of the quartz cup experience rapid or uneven temperature changes, internal stress may develop.
For example, a user might finish a heating cycle and immediately wipe the hot quartz cup with a cotton swab soaked in cold isopropyl alcohol.
This creates a sudden temperature difference between the hot heating surface and the cleaning solution. Depending on the material, temperature, and existing stress, the sudden cooling may contribute to cracking.
How to prevent it:
-
Allow the quartz cup to cool completely before cleaning.
-
Never apply cold cleaning liquid to a hot heating cup.
-
Avoid placing a hot atomizer on a cold, wet, or otherwise unsuitable surface.
-
Do not use water or other liquids to cool the heating cup rapidly.
The key principle is simple: let the heating component return to room temperature naturally before cleaning it.
Reason 2: Excessive Wattage or Prolonged Heating
The recommended operating range for the Longmada Motar 1 coil is 20–25W.
Using a power setting above the recommended range may increase the risk of overheating and shorten the service life of the heating component.
Prolonged heating can also increase thermal stress, especially when multiple heating cycles are performed without sufficient cooling time.
Some users assume that higher wattage will always produce better performance. In practice, excessive power may cause unnecessary stress on the coil rather than improving the overall experience.
How to prevent it:
-
Keep the power setting within the recommended 20–25W range.
-
If using an adjustable third-party battery, verify that the actual wattage is set correctly.
-
Avoid unnecessarily long heating cycles.
-
Pause after three consecutive heating cycles and allow the device to cool for a few minutes before using it again.
-
Avoid repeated heating when the atomizer is already excessively hot.
For the best results, Longmada recommends pairing the Motar 1 coil with a compatible battery that can provide suitable power output.
Reason 3: Cleaning the Quartz Cup While It Is Still Hot
Cleaning is essential for maintaining an atomizer, but cleaning at the wrong time can damage the heating component.
A hot quartz cup may be more vulnerable to sudden temperature changes. Applying alcohol, water, or another cool liquid immediately after heating may create thermal stress.
Scraping the cup while it is hot can also damage the component, particularly when hard tools are used.
How to prevent it:
-
Turn off the device and disconnect it from the battery before maintenance.
-
Place it on a stable, heat-resistant surface.
-
Wait until the heating cup has cooled completely to room temperature.
-
Use a soft cotton swab to remove accessible residue gently.
-
If using isopropyl alcohol, follow the cleaning instructions for the specific components and allow all cleaned parts to dry completely before reassembly or use.
Do not immerse the battery in cleaning liquid. Avoid allowing liquid to enter electrical connections or the battery housing.
Most importantly, never use alcohol or another flammable cleaning agent near an active heating element.
Reason 4: Scraping the Cup With Metal Tools or Hard Objects
Wax residue can accumulate inside the quartz cup during normal use.
When residue becomes difficult to remove, some users may try to scrape it away with a metal dab tool, needle, screwdriver, or another hard object.
Applying excessive pressure to the quartz surface may cause scratches, chips, or cracks. Contact with the heating element may also damage or displace internal components.
How to prevent it:
-
Use a soft cotton swab for routine cleaning.
-
Remove residue gently instead of scraping aggressively.
-
Do not strike the quartz cup with metal tools.
-
Never force a tool into the heating cup to remove stubborn residue.
-
Replace the coil if the cup is chipped or cracked rather than attempting to repair it.
A quartz heating cup should be handled gently, even when it appears solid and durable.
Reason 5: Dropping the Device or Applying Excessive Mechanical Force
A quartz cup may crack because of impact even when the exterior metal housing remains intact.
For example, the atomizer might be dropped onto a hard floor, knocked against a table, or subjected to pressure while being installed or removed.
A crack may also develop if the heating component is forced into an unsuitable position.
How to prevent it:
-
Handle the atomizer carefully during installation and cleaning.
-
Avoid dropping the device or striking it against hard surfaces.
-
Do not force the coil into the metal base.
-
Ensure the replacement component is compatible with the intended atomizer.
-
Store the device securely when it is not in use.
If the coil has been dropped or subjected to a strong impact, inspect it carefully before its next use. Do not continue using it if damage is visible.
Reason 6: Incorrect Assembly or an Incompatible Battery Setup
Incorrect installation may create electrical connection problems or mechanical stress.
The Motar 1 coil should be installed into its atomizer base before the assembled atomizer is connected to the battery.
When installing or replacing a coil, make sure the device is turned off and disconnected from the battery.
Recommended installation sequence:
-
Turn off the battery and disconnect the atomizer.
-
Install the compatible Motar 1 coil into the atomizer base.
-
Check that the component is correctly seated without forcing it.
-
Attach the assembled atomizer to the compatible battery.
-
Verify that the power setting is appropriate before use.
The Motar 1 coil is designed for 20–25W operation. If you use a third-party battery, confirm that it supports the required power range and operates correctly with the atomizer.
Do not assume that every 510-thread battery is suitable simply because its connector fits.
Incorrect assembly does not necessarily cause quartz cracking directly, but it can create other problems that should be ruled out during troubleshooting.
Reason 7: A Defective or Damaged Component
Although user practices and operating conditions can contribute to cracking, a manufacturing defect or damage that occurred during shipping should not be ruled out.
If a coil develops a crack after only one or two normal uses, especially when the recommended power range and cooling procedures have been followed, further inspection is appropriate.
Consider the following questions:
-
Was the coil visibly damaged when it arrived?
-
Did the crack appear during heating or after cooling?
-
Was the device operated within the recommended 20–25W range?
-
Was the heating cup cleaned while hot?
-
Was the atomizer dropped or struck against a hard surface?
-
Is the crack located inside the quartz cup, around the rim, or near the connection area?
These details can help distinguish possible thermal damage, physical damage, and a potential product defect.
At Longmada, we recommend documenting early coil failures with clear photos or a short video. This gives the support team more information to investigate the problem instead of assuming that every crack has the same cause.
2. How to Prevent Your Motar 1 Quartz Coil From Cracking
Correct maintenance cannot guarantee that a quartz component will never crack, but it can help reduce avoidable stress and premature damage.
Follow these practical recommendations.
Tip 1: Use the Recommended 20–25W Power Range
The Motar 1 coil is designed to operate at 20–25W.
Using a compatible battery and the correct power setting helps avoid unnecessary overheating.
If you are using a third-party mod, check the wattage before activating the device. Do not increase the power simply to produce more vapor.
Tip 2: Avoid Too Many Consecutive Heating Cycles
Repeated heating can raise the temperature of the atomizer and its surrounding components.
After three consecutive heating cycles, pause for a few minutes and allow the device to cool.
If the atomizer remains unusually hot, allow additional cooling time before continuing.
Avoid treating the recommended wattage as permission to heat continuously without breaks. Both power and heating duration matter.
Tip 3: Let the Coil Cool Completely Before Cleaning
This is one of the most important maintenance habits.
Never clean the quartz cup immediately after a heating cycle. Wait until it has returned to room temperature before using a cotton swab or an appropriate cleaning agent.
Do not attempt to accelerate cooling with water, alcohol, ice, or another cooling method.
Tip 4: Use Small Amounts of Material and Avoid Unnecessary Heating
Loading an appropriate amount of material helps reduce unnecessary heating time and residue accumulation.
Use short, controlled heating cycles rather than activating the device longer than needed.
Avoid repeatedly heating an empty chamber without a specific instruction from the manufacturer.
Tip 5: Clean Gently and Regularly
Allowing residue to accumulate may make cleaning more difficult.
After the device has cooled completely, gently remove accessible residue with a cotton swab.
For more thorough cleaning, use only a cleaning method compatible with the specific component. Ensure that all parts are completely dry before reconnecting the atomizer to a battery.
Never scrape the quartz cup aggressively or use sharp objects to remove stubborn buildup.
Tip 6: Avoid Physical Impact
Quartz can break when subjected to impact or concentrated pressure.
Keep the atomizer away from hard edges, avoid dropping it, and store it in a secure location when not in use.
During installation, tighten components carefully without applying excessive force.
Tip 7: Inspect the Coil Regularly
Before use, look for visible cracks, chips, unusual discoloration, or other signs of damage.
If you notice a crack in the quartz heating cup, stop using the coil and replace it.
Do not attempt to glue, seal, or otherwise repair a cracked heating component. Adhesives and improvised repairs are not suitable substitutes for a properly functioning replacement part.
3. What Should You Do If Your Motar 1 Coil Has Already Cracked?
If your quartz coil has developed a crack, the safest approach is to stop using it and investigate the cause.
Follow these steps.
Step 1: Stop heating the damaged coil.
Do not continue using a cracked quartz cup. Further heating may worsen the damage.
Step 2: Allow the atomizer to cool completely.
Place the device on a stable, heat-resistant surface and wait until it has returned to room temperature.
Step 3: Inspect the damage without applying force.
Look at the quartz cup and surrounding components. Do not press on the crack, bend the heating component, or attempt to separate parts that are stuck.
Step 4: Document the problem.
Take clear photos showing the crack, the complete coil, and the atomizer assembly.
If possible, provide information about the number of uses, the battery model, the wattage setting, and the cleaning method.
Step 5: Contact Longmada customer support.
If the coil cracked after only a few uses under normal operating conditions, send the details to the support team for review.
The team can help determine the appropriate next step based on the available evidence and applicable product support policy.
4. How Long Should a Motar 1 Quartz Coil Last?
There is no guaranteed lifespan for a quartz coil.
Its service life depends on several factors, including:
-
Frequency of use
-
Length of each heating cycle
-
Power setting
-
Cooling time between sessions
-
Cleaning habits
-
Physical handling
-
Material buildup
-
Individual component condition
A coil used occasionally with careful maintenance may last longer than one subjected to frequent, prolonged heating.
For this reason, it is better to focus on proper operating conditions and visible signs of wear rather than promise a fixed number of days, weeks, or heating cycles.
Replace the coil when it becomes damaged or no longer operates properly.
If a new coil develops a crack unusually quickly, contact the manufacturer rather than assuming that rapid failure is normal.
