Jeff December 11, 2024 for Model Number FASG7074NW0 P/N 13458770 original reads 48.5K OHMS when it should be 55-60K OHMS. I replaced with same P/N from supply house and its reading was 12.5K OHMS. Dryer would not light with new part (gas dryer) reinstalled old thermistor and dryer lit but takes far too long to dry. All other parts replaced and vent system cleaned out completely from roof to dryer. Where can I find a thermistor with the proper resistance?
1 Answer Jeff, the thermistor OEM15467370 should have a resistance of 50K Ohms at a room temperature of 76 degrees Fahrenheit. Read More...
Patricia April 18, 2024 for Model Number FFSE5115PA1 This dryer continues to have an EF1 error code, which indicates a blocked vent. The entire vent was cleaned out. The dryer was disassembled and cleaned and the error code still came up. Finally, the vent hose was disconnected and while running, the error code came up. What sensor indicates vent blockage to the main control?
1 Answer Patricia, The control thermistor 134587700 would be the most likely cause for this issue. Read More...
Anthony September 16, 2023 for Model Number ffre1001pwo dryer runs great but no heat i changed heating elements and the 2 therastats on element but no heat
1 Answer Anthony, You will want to check to see if the control thermistor is good and if it is then check the timer to make sure that there is 120 vac coming off of it to the heater. If there is power from the timer then the issue will be with the centrifugal switch on the motor. Read More...
Edwin September 03, 2023 for Model Number Frigidaire affinity Thermistor reads 48 on 200k o and will go down with heat. I have replaced the heater element .the heat will not turn off. Is my Thermistor bad or is there a other problem
1 Answer Edwin, We will need to have the model number of your unit in order to properly assist with your question. Please resubmit your question with the model number. Read More...
Mike N April 13, 2023 for Model Number FFRE4120SW I have a thermistor that has gone bad I guess. It’s reading 40 ohms when set at 200k on the multimeter. Probably 75*. Do I need a new one. What would one cost? Thanks
1 Answer Mike, Based on your indoor temperature the thermister would be out of spec. 5304511428 is your replacement Read More...
Bruce December 05, 2022 for Model Number Kenmore 41788042700 I have a 12 year old Kenmore model 41788042700 electric dryer. While I recently had the unit apart to replace the rear bearing and front felt seals (thanks, by the way, for your great repair videos!), I checked the original factory thermistor impedance to make sure it was functioning properly. The reading on my digital meter which was set at 200K and at approximately 76°F room temperature was 46K ohms. Is this within the proper functioning range for the Frigidaire / Electrolux thermistor part #134587700 or does it need to be replaced at this time? Thank you for your help!
Mikej June 21, 2021 for Model Number AEQ8000FS0 11 year old dryer stopped heating after replacing drum bearing and adding new belt - runs no heat for 10 mins then shuts off and flashes three lights at right - error code E5b - no heating (duh!). continuity at thermal fuse, high limit thermostat and element (no breaks). Thermistor reads about 70K Ohm when I can get my junk HFT cen-tech meter to give a reading - should be 50K - but would think this would only make dryer run hotter than it should? Is there a way for me to test the control board? Seems like most of the solutions on tech sheet for error codes are to replace electronic control.
1 Answer Mike, Here are the steps to take to find out what is going on with the unit. Position cycle selector to NORMAL, temperature selector to HIGH HEAT and touch START. Measure voltage across terminals on relay RL2 (heater relay) on electronic control. If meter reads 240V on electric models and 120V on gas models, replace electronic control. If meter reads zero, remove power from dryer. Disconnect wire going to NO terminal on the relay RL2. Reconnect power and measure voltage drop between terminal COM on relay RL2 and neutral. If meter reads zero, wire between incoming line and relay RL2 is open. If meter reads 120V, check the rest of the heater circuit. Read More...
Martin March 18, 2021 for Model Number FASE7021NW0 Hello. My dryer gets hot such that the top is very warm to the touch and the clothes are hot inside. This happens even when the controls are set to air dry. I don't see any error codes.
1 Answer Martin, it would be recommended that the dryer duct and the vent are ensured that they are clear of lint build-up. From there, it would be recommended that the main control 809160802 is tested for continuity when the power supply cord is unplugged from the wall outlet. At the connection J5, pin 1 would be tested to pin 2 for continuity. Then from the connection J5 pin 3 to the connection J7 pin 1 would be tested for continuity. Finally, the connection J7 pin 2 to pin 3 would be tested for continuity. If there is continuity at any of the test points, the main control has failed. If there is not continuity, the heater element would need to be tested for continuity to the chassis to identify if there is a grounded point in the heater circuit. Read More...
Mark February 22, 2021 for Model Number AEQ7000ES1 My dryer heats for about 5-10 minutes and then the display shows a code of “Ad” indicates the auto dry cycle has been selected. The dryer control is trying to determine the needed dry time. I replaced the heating coil and cleaned all the lint from the dryer. Same results. I have to cycle the cloth 2-3 times to get them dry. I tested the Thermistor and it reads 38 ohms at 68 degrees. The Specs say that the resistance should be between 47K Ohm and 66K Ohm at room temperature (68-77° F). Would being 9 ohms off cause this issue? Should I replace the Thermistor?
1 Answer Mark, as the thermistor 134587700 is only reading 38O and is not reading 47,000 O, this would certainly indicate a failure with the thermistor especially if the resistance does not change with heat. Read More...
Koz November 22, 2020 for Model Number FARG1011MW1 Dryer runs, but no heat. Thermal limiter on gas burner tube was blown, but thermistor (pn# 134587700) reads 70K ohms (and should read 50K ohms) is that too high a reading to account for fluctuation in room temperature? And could a bad thermistor cause the thermal fuse to blow? (Duct appears clean)
1 Answer Hello Koz, the thermistor is out of range the replacement part is 134587700. It is signaling the control the air temperature is cooler then it actually is. Read More...
