How to Install Conversion Kit MAL9000AXX in a Whirlpool Dryer
If your Whirlpool dryer is not working properly after a fuel change or setup change, you may need to know How to Install Conversion Kit MAL9000AXX the right way. A conversion kit affects how a gas dryer burns fuel. That makes this job more serious than a basic lint filter or belt repair.
You will work around gas parts, an orifice, and regulator settings. Small mistakes can cause poor drying, soot, delayed ignition, or a leak. Treat the job with care from the first step.
Conversion Kit MAL9000AXX is linked to Whirlpool dryer service needs where a dryer must match the correct fuel type. Your dryer may use LP, also called propane, or natural gas. These fuels do not use the same orifice size or regulator setup.
This guide walks you through the safety checks, prep work, install flow, and final testing. You should stop and call a licensed technician if anything feels unclear.
Before You Start
A gas dryer must match the fuel supplied to your home. LP and natural gas are not interchangeable without the right conversion parts and setup. The flame, pressure, and gas flow all depend on correct parts.
Conversion Kit MAL9000AXX should only be used where your dryer model and service information support it. Do not force a kit into a dryer that does not match your model tag or manual. If your manual does not list the kit, pause and verify before you open the dryer.
Use your dryer model number when checking service information. The supplied compatible models are:
| Model Number |
|---|
| LDE7304AGE |
| MDE8057AYW |
| MDE9706AYW |
| MDE9766AYW |
| MDG3000AWW |
Model numbers can look close but still use different parts. Check the full number on the dryer tag. Do not rely on a partial number from a receipt or listing page.
You can also review Whirlpool support material through the Whirlpool Product Help Library or the Whirlpool Service and Support manual lookup. Use those sources to confirm model-specific steps before you change any fuel system part.
Gas Safety Comes First
Gas work needs a higher safety standard than many dryer repairs. You are not just replacing a broken part. You are changing how fuel enters and burns inside the machine.
Turn off the gas supply valve before starting any work. The valve handle should be across the pipe when off. If you smell gas before starting, leave the area and contact your gas provider or emergency service.
Unplug the dryer before removing panels. A gas dryer still uses electric power for controls, the motor, and ignition parts. Cutting power helps prevent shock and accidental startup.
LP and natural gas use different orifice sizes. The orifice controls how much gas reaches the burner. LP, or propane, usually needs a smaller opening than natural gas because it runs at a different energy level and pressure. If the wrong orifice is installed, the dryer may burn too hot, burn too rich, or fail to ignite right.
The regulator also matters. A dryer regulator must match the fuel type and pressure requirements for LP versus natural gas. The regulator controls gas pressure before fuel reaches the burner. A wrong regulator setting can cause weak heat, noisy ignition, soot, or unsafe combustion.
After install, test all connections for leaks. Use a soap-and-water solution or a gas leak detector. Never use a flame to check for leaks. Bubbles at a joint mean gas is escaping.
Many LP to natural gas or natural gas to LP conversions require certification steps. Some also require a rating-plate update or conversion label. Follow the dryer manual, kit instructions, and local code. Call a licensed gas technician if uncertain about any step. A licensed technician can verify pressure, leak safety, and compliance.
Tools and Supplies You May Need
Your exact tool list depends on the dryer cabinet and burner layout. Since no model-specific tool list was supplied, keep the list general.
You may need:
- Nut driver set
- Screwdriver set
- Adjustable wrench
- Open-end wrench set
- Work gloves
- Flashlight
- Soap-and-water solution
- Gas leak detector, if available
- Small container for screws
- Dryer manual or service sheet
Do not use damaged tools on gas fittings. Rounded tools can strip fittings and create leaks. If a fitting resists, stop and inspect it. Never keep twisting until the part bends or cracks.
Keep the work area bright and clean. Small orifices and screws are easy to lose. Place removed parts in order so you can track what changed.
Difficulty and Time
This repair is a medium-difficulty job. Plan on 30 to 60 minutes if the dryer is easy to access and you have the correct information ready.
The job may take longer if the dryer sits in a tight laundry closet. It may also take longer if the gas line is stiff, the manual is missing, or the burner area has heavy lint.
Do not rush the leak test. That final check matters as much as the part swap. A fast repair with a poor test is not a safe repair.
When This Kit May Be Needed
A conversion kit may be needed when a dryer moves between homes with different fuel supplies. It may also be needed when a home changes from natural gas to LP, or from LP back to natural gas.
The symptom list supplied for this article is broad: dryer not working properly. That can mean many things. A dryer that uses the wrong fuel setup may show heat issues, ignition trouble, or poor drying. It may run but fail to dry clothes within a normal cycle.
Fuel mismatch can also cause flame problems. You may notice unusual burner behavior, soot, or a smell that does not seem normal. Stop using the dryer if you suspect a gas or combustion problem.
A conversion kit will not fix every dryer issue. If the dryer has no power, a broken belt, a failed door switch, or a clogged vent, the kit is not the first repair. Confirm the fuel setup before blaming the conversion parts.
Signs You Should Stop Before Installing
Some warning signs mean you should pause and get help. Gas repair is not the place to guess.
Stop before installing if:
- You smell gas near the dryer.
- The shutoff valve does not close fully.
- The gas connector is kinked or damaged.
- The dryer model tag does not match your notes.
- The manual does not support the conversion.
- The burner parts look corroded or bent.
- You cannot identify the orifice or regulator.
- The kit instructions conflict with the dryer label.
- You do not have a leak test method ready.
A safe stop beats a risky finish. If any point feels wrong, call a licensed technician.
Conversion Decision Matrix
Use this table before you start. It helps you decide whether to continue, verify, or stop.
| Situation | What It Means | Best Next Step |
|---|---|---|
| Dryer model matches your verified service information | You may be ready to proceed | Continue with safety prep |
| Dryer model is close but not exact | Compatibility is not confirmed | Verify before opening dryer |
| Fuel type changed from natural gas to LP | Orifice and regulator setup may need change | Follow kit and manual |
| Fuel type changed from LP to natural gas | Different orifice and regulator setup may apply | Follow kit and manual |
| You smell gas | Possible leak or unsafe connection | Shut off gas and get help |
| You cannot test for leaks | Install cannot be verified safely | Do not continue |
| Rating label needs update | Conversion record may be required | Follow code and manual |
This matrix does not replace the manual. It helps you spot risk before the dryer is apart.
How to Install Conversion Kit MAL9000AXX Safely
Common Pitfalls During This Repair
The biggest mistake is treating this like a normal part swap. A conversion kit changes fuel flow. That means small details matter.
Another common mistake is mixing LP and natural gas parts. The orifice may look small and simple, but the opening size controls fuel volume. The wrong part can create unsafe combustion.
Some people skip the regulator step. That can leave the dryer with the wrong pressure setup. The dryer may still run, but it may not run safely.
Others skip the leak test because the connection “feels tight.” Tight does not always mean sealed. You need bubbles or a detector test to confirm the joint.
Many errors start with the wrong model number. A dryer model tag gives the best information. Marketing names, store names, and partial numbers can mislead you.
What to Check After Installation
A proper test includes more than starting the dryer. Watch how the dryer behaves during the first full heat cycle.
Check for:
- No gas smell near the dryer
- No bubbles at tested gas joints
- Stable burner operation
- No soot or smoke
- Normal airflow at the vent
- No rattling panels
- No loose screws
- Dryer heating during the cycle
Poor airflow can make a good repair look bad. Clean the lint screen and check the vent path. A blocked vent can cause long dry times even when the gas conversion is correct.
If the dryer still does not work properly, do not keep changing gas parts. Test the basics first. Power, airflow, controls, ignition, and venting all affect drying.
Model Number Check
The supplied model list includes LDE7304AGE, MDE8057AYW, MDE9706AYW, MDE9766AYW, and MDG3000AWW. Use that list as a starting point, not as a substitute for the dryer tag and manual.
A full model number may include extra letters or numbers after the main string. Those extra characters can matter. They may point to a production change or cabinet version.
If your model number is not clear, take a photo of the tag. Good lighting helps. Do not guess from memory. One wrong character can send you toward the wrong part.

When to Call a Pro
You should call a pro if you cannot shut off the gas supply valve. You should also call if the gas connector looks damaged or the valve will not seal.
Bring in help if you do not understand the LP and natural gas difference. Fuel type affects the orifice and regulator. Guessing can create a serious hazard.
A pro should also handle the job if local code requires certification. Some areas require a licensed technician for gas conversion work. Others require a label or rating-plate update after conversion.
Call for service if the dryer smells like gas after repair. Do not run another test cycle to “see if it clears.” Turn off the gas and get help.
