I have a Whirlpool Cabrio Dryer, Model # WED7600XW. The dryer started to become really hot no matter what heat setting it was on. I replace the thermal fuse (after it burnt out), but the heat problem still exists? I have removed and cleaned the entire blower and vent area. Could it be the thermistor or the thermostat?
Thanks for your help!
The most likely thing to check with the issue that you are having would be the thermistor and see if the resistance checks ok. This can be checked from the control board on the outlet temp Connector P4 pin 3 and return P4 pin 6 which when disconnected from the board should have a resistance rating of 10K ohms at room temperature. You would also check the inlet temp thermistor P4 pin 2 to inlet temp return P4 pin 1 for 50k ohms of resistance at room temp. One of these thermistors being faulty would most likely be the cause of your issue.
My cabrio is running but with no heat. Checked the vents and power supply. Should I replace the thermostat?
Answer Hello Mary. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermostats and see if they are good. if so, you may need to replace the power relay board on the unit. You can test these with a multi-meter TJMA-DM1. They should read closed for continuity. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My dryer gets an AF error code. I have checked the exaust vent and inside the dryer. What could be the cause and repair for this problem?
Answer Hello Tim. AF flashes if a restricted airflow condition exists.
Check to make sure the lint screen is clean, the
door seal is in place and the vent is not
obstructed. Also, check the blower wheel and clean the venting inside the dryer.
My dryer will run a little bit then shuts off. When it stops it gives a code F-40. Could this be a thermostat?
Answer Hello Jim,
The F-40 fault code is a communication error between the machine control board and the motor control board. The first thing you should do is unplug each connector and reconnect them one at a time. This could correct the issue if it is just a connector not making good electrical contact. If this doesn't correct the issue, go to page 8 of the tech sheet inside the machine. The procedure is as follows:
1. Access the motor control electronics. 2. Visually check the communication harness. The communication harness is a three-wire harness that connects between the two electronic control assemblies. Make sure it is fully inserted into both electronic controls. 3. If the communication harness looks OK, go to step 4. 4. Visually check the wire harnesses connected to the motor control electronic assembly. Make sure they are clean and fully inserted into the control. ? If the connections look OK, go to step 5. 5. Remove the MC2 blower motor electrical connector from the blower motor electronic control. 6. Measure the resistance between the following terminals on the connector: pins 1 to 3, 1 to 5 and 3 to 5. The resistance should be between 55 and 65 ohms. ? If the resistance looks OK, go to step 7. ? If the resistance is much greater than 65 ohms, go to step 7. ? If the resistance is much less than 55 ohms, replace the blower motor. 7. Visually check the wire harness connection at the blower motor. ? If the connections look OK, check for obstructions in the blower housing. Make sure blower fan rotates freely. ? If no obstructions are found, replace the motor control electronic assembly.
what makes drier get too hot
Answer Mark, usually a"hot" dryer is due to a clogged or restricted exhaust vent pipe or hood. You may want to disconnect the exhaust and run the dryer, the average exhaust temp. should be 155 dgrs.F. on a regular or high temperature setting.
my dryer comes on, but won't run at all. would the thermostats cause this or is this a motor issue?
Answer Mike, No, thermostats would not normally cause the dryer to not run. But it's probably not a motor issue either. You should check the thermal fuse 3392519 and belt switch 279782 if either of these switches or wires are damaged or open, the fryer will program, but the motor won't start or run. The other possibility is a faulty control board W10110641, bu that should be the last resort.
My drier keeps blowing the fuse. Have checked and cleaned all lint and replaced plug and plug in. About 15 min into drying cycle fue blew again. I am thinking i need a new thermistor?
Answer Hello Gracia,
Check all connections before replacing components. Look for broken or loose wires, failed terminals, or wires not pressed into connectors far enough. I've included the tech. sheet for troubleshooting purposes. Put the unit into the diagnostic mode and pull the fault codes as per the instructions. If the only fault code is for past power failures, replace your breaker/fuse holder.
The thermistor is used for moisture sensing purposes and will not cause this complaint.
