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
This bimetal limit switch monitors a radiant surface element's temperature and opens the circuit if it overheats, helping your cooktop maintain safe, consistent heating while protecting wiring and controls from damage. What it does:
We initially called a repair company who immediately diagnosed the fan, without opening up anything. They quoted $550 to repair. $159 of that was the fan part. Plus they told me the parts come from overseas and will take 2 week to arrive. I researched the model number and can part and found exactly what I was looking for on your site. Plus there were diagrams and forum discussions that boosted my confidence on repairing ourself. Using your parts diagrams and our manual information, we pulled... Read more
Dryer not heating or overheating? This thermostat regulates temperature during the drying cycle. Common DIY repair that restores proper heat control.
Did it myself. Read more
Fix a dryer that won't heat with this outlet backup thermostat. Mounts on exhaust duct for over-temperature protection. DIY repair in under 1 hour.
Checked vent first to see if there was a blockage. Removed top, front and drum of dryer. Replaced all sensors including flame detection and gas valve coils. Re-assembled and tested. Dryer was now heating Read more
Fix ice buildup and cooling issues with a new defrost thermostat. This bi-metal switch monitors evaporator temperature to prevent frost accumulation.
Unplugged freezer, left door open to defrost, after one day was able to remove back panel, coils still iced up. Left door open another 24hrs to allow the coils and wiring to clear of ice. Then located the defrost thermostat, unplugged and removed. Placed the defrost thermostat in a different working freezer overnight, checked with a continuity testor, getting intermittent good readings, replaced with a new defrost thermostat. Plugged in the freezer marked the defrost timer position, checked for... Read more
This line fuse protects the appliance's incoming power circuit by opening if an overload or short occurs. Replacing a blown fuse can help restore power once the underlying issue is corrected, preventing further damage to sensitive components.
Tested the High Voltage Capacitor which showing no capacitance and no resistance. Replaced it together with the diode and the line fuse no longer blew and the microwave is back in service. Read more
Fix a dryer that overheats, won't dry completely, or stops mid-cycle. This cycling thermostat regulates heat to prevent damage. DIY-friendly repair.
I replaced the main parts for the dryer cycle system Read more
This heater harness installs in the refrigerator's fresh food section. It provides defrost heat and the correct wiring connections to clear frost from the fresh food evaporator, restoring airflow so the compartment cools evenly and reliably.
I replaced the evaporator fan after using a steam gun to defrost the evaporator and ensuring the drain wasn't clogged. After assembling, I noticed the refrigerator wasn't performing a defrost cycle. After testing the heater, I determined the main board relay was malfunctioning and not supplying the voltage to the heater. After correcting this, the ice maker wasn't making ice still and after troubleshooting it, I determined the dc motor was stuck. I replaced the ice maker and the... Read more
Oven won't power on after self-clean? This thermal fuse cuts power when temperatures get too high. Common fix for no-power issues after cleaning cycles.
Replaced open circuit thermistor at back of unit to restore power to stove. Replaced thermal fuse behind control panel due to high resistance in original one. Stove now operational. 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
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
Dryer won't heat or overheats? A faulty safety thermostat fails to regulate temperature. Test for continuity with a multimeter; moderate DIY repair.
Removed lid. Removed switch panel. Suspected open circuit in thermal fuse. Tested it with a multimeter first to confirm it had an open circuit. This part is obsolete. Contacted manufacturer and found part supercedes to a different part number Ordered part. (This website is very efficient. The part arrived with the 1.7 day promise time.) new fuse bracket is slightly larger due to supercession. Marked bolt hole locations and drilled new. Installed fuse. Re-assembled dryer in reverse order.... Read more
Oven won't heat or can't hold temperature? This thermal switch monitors oven temperature and protects internal components. Common fix for heat issues.
After 2 repair men, many parts replace it still didn't work, Did research on line and found out the thermal fuse would need to be replace.. Read more
Oven won't unlock after self-clean or control panel is blank? This thermal fuse thermostat protects your range. Easy DIY fix in under 30 minutes.
Based on information found at AppliancePartsPros, I determined that the it was most likely the thermostat (thermal fuse). I removed the rear panel and tested the fuse for continuity and it was bad. I used a jumper wire to bypass the fuse and plugged the range back in. The panel turned on and the oven unlocked. I then removed the thermostat and looked up the replacement part and ordered.

This temperature sensor monitors internal refrigerator temperatures and relays them to the control, helping the unit maintain consistent cooling. Replacing a failed sensor restores accurate temperature regulation and more reliable operation. What it does:
I've cleaned the drain tube numerous times. Always freezes and plugs. Added a defrost tab down into drain tube, missing from factory. This time defrost heater bad. Replaced heater, bi-metal switch and temp sensor. Great service and next day receipt of parts. Thanks ! Read more
This is a thermistor-style temperature sensor that monitors the internal temperature inside the refrigerator compartment and sends readings to the main control board. The control board uses this data to regulate the compressor and cooling cycles to maintain proper temperatures. Replace this sensor if the refrigerator is running too warm, too cold, not cycling correctly, or displaying temperature-related error codes.
Using service manual, obtained from this site, I verified with meter that this was the error. I ordered the defrost sensor. The part arrived the next day. Most of the time to repair was unloading, cleaning, and reloading the refrigerator. Read more
