The Pressure Sensor is an OEM replacement part for LG dryers. This sensor monitors the airflow or pressure within the dryer, helping to regulate drying cycles and ensure efficient operation. By detecting blockages or changes in airflow, it plays a critical role in maintaining proper performance and preventing overheating.
Over time, the pressure sensor can fail due to wear, electrical issues, or buildup of lint and debris. Damage to the sensor or its connections can cause the dryer to operate inefficiently or stop functioning altogether.
Symptoms of a bad pressure sensor include:
This OEM LG part is also compatible with Sears/Kenmore dryers.
Dishwasher not heating or drying dishes? This high limit thermostat monitors water temperature and prevents overheating. Easy DIY fix with basic tools.
I took and ohm meter to the heating element and figured out that was ok. Went to the thermostat and it was toast. Easy fix. Read more
Dryer not heating or shuts off after a few minutes? A faulty thermostat often causes temperature regulation failure. Easy DIY fix with a multimeter test.
I checked the continuity on the thermal fuse (which was blown) and knew that it needed to be replaced. This made me question why it blew (i.e. what caused it to fail). I checked continuity on the thermostat (high limit) as well as the thermostat for the element. Both passed a continuity test, so I removed the high limit thermostat to inspect it and could hear it rattling inside. This leads me to believe the spring inside had failed, so I replaced this thermostat as well. Put it back... Read more
Microwave won't turn on or has no power? A blown fuse is often the cause. This safety component protects against electrical surges and short circuits.
I have a Jenn-Air microwave that didn't turn on and had no lights. It just stopped working completely. I unplugged the unit and had to remove the rear cover using a *security screw kit* that prevents people from opening the rear panel. Once opened, I removed the fuse and testing it with an OHM reader to determine that the fuse went bad. But I also had to determine why the fuse blew and noticed a sticky oily substance under the Capacitor. I used a rubber glove and needle nose pliers to... Read more
Fix a dryer that won't heat or shuts off after 10-15 minutes with this thermal cutoff fuse. Common DIY repair for temperature detection issues.
I replaced the thermal cut-off sensors and the cutoff-Tml Read more
This sensor harness connects the dryer's moisture sensor bars to the main wiring, helping the control or timer read moisture levels so Auto Dry cycles can advance and deliver consistent, reliable drying performance.
Replaced 3 low cost parts as advised by Appliance Parts Pros. Saved the labor costs by troubleshooting and replacing parts with their great videos. Works like new, and took 15 minutes to complete the repair. Read more
This internal-bias thermostat regulates dryer drum temperature by cycling the heat on and off, helping maintain consistent drying performance and protect against overheating.
Cleaned exhaust duct, but only from the dryer/laundry room side. Replaced thermal fuse. Unit worked for about two loads and thermal fuse blew again. This time I cleaned the exhaust vent on the roof of my 2-story house. It was found to be partially obstructed and I was able to remove a significant amount of lint from it. Also, I researched the problem and followed someone's advice to replace the cycling thermostat together with the thermal fuse if the thermal fuse blows. So far it has been... Read more
Oven won't heat or shuts off during use? A blown thermal fuse cuts power to prevent overheating. Simple diagnosis with a multimeter, quick replacement.
Oven won't heat after self-clean cycle? This safety thermostat protects control components by shutting off power when temperatures exceed safe limits.
Microwave won't heat or is completely dead? A failed thermal cutoff thermostat often causes no power or heating. DIY repair in 30-45 minutes.

Fix a dryer that won't shut off automatically or has temperature control issues. This thermistor sensor monitors heat levels for proper cycle operation.
I replaced the thermostat. The bearing on the motor was getting loose, so I changed the motor to. The repair took about 2 hours. There are some good re[air videos on the parts web site. Read more
Genuine Whirlpool OEM moisture sensor bar for electric and gas dryers. Works with a second sensor strip to detect humity/moisture as clothes tumble past. The control board reads the signal to determine remaining moisture and ends the cycle automatically at the target dryness level — preventing over-drying and reducing energy use.
Common Failures
Purchased a new sensor from AppliancePartsPros.com. Installed new part - Problem fixed. Read more
Dryer won't heat? A failed thermal limiter opens the heating circuit when temperatures exceed safe limits. Simple DIY fix restores heat in 15-30 minutes.
The thermal cutoff went bad because of lint being trapped in dryer vent and blocked air-flow from dryer. Removed accumilation of lint and installed new thermal -cutoff and thermostat and dryer now works great. Read more
Microwave won't power on or has no display? This thermostat monitors internal temperature to prevent overheating. Easy 15-minute DIY fix for most models.
I attempted to diagnose the four thermostats/thermal switches in the microwave....two right behind the control panel, one on top of the cooking cabin, and one under a metal shroud above the magnetron. While checking continuity with a voltmeter, i questioned one of them behind the control panel and the one above the magnetron. I then noticed a burn mark on the plastic connector sleeve for the one above the magnetron. I took a scrap piece of 14 gage copper wire and beat the ends flat with a... Read more
Fix dryer heating issues with this thermistor temperature sensor. Solves intermittent heat, cycle errors, and poor drying. Easy DIY repair.
Replaced all sensors, limiters, thermistors, thermostat. Works great now. Read more
Microwave won't turn on or has no power? A failed thermostat often causes complete power loss. Moderate DIY repair requires disassembly to access.
I checked for the reasons there was no power to the microwave. Then I talked with the technician at AppliancePartsPros who stated that it was most likely a blown or defective fuse. My LG microwave has two thermal fuses, a fuse assembly with two prongs and a short (1 inch) barrel type fuse. I replaced all of them after viewing YouTube videos and then reviewing the diagram for my microwave on the AppliancePartsPrps website. That was very helpful in locating where the fuses were installed. It... Read more
