If your Frigidaire dryer is not heating this repair guide can help. If you have
a dryer no heat problem you may have a bad heating-element. However there are
other things that may cause this so use this repair guide to help diagnose the
problem correctly. This page is for typically a Frigidaire dryer, not a top end
model as in a front loader set.
The first thing you must do to diagnose this problem is to disassemble the
dryer by following these steps.
1. Disconnect power to the dryer.
2. Using a screwdriver press in on the two clips between the front and the
top. This will release the top and allow you to lift the top up.
3. Remove the screws pointing forward that hold the front on.
4. Prize the front off.
5. Remove the yellow stop in the front of the drum.
6. Disconnect the belt.
7. Lift straight up on the back of the drum until you feel it pop out of the rear bearing and remove the drum.
Once the drum is out you can visually inspect the heating element. If it is bad it will be broken. Sometimes this break will be hard to spot so gently tug the element all the way around to see if there is a break. If you don’t see a break you will need to test it with an ohmmeter to be sure. You should get around 11-12 ohms between the terminals (give or take); if it is open replace it. Be sure to disconnect the wires before testing or you may get a false reading. Then test from each terminal to ground and it should be open. If you get an ohm reading to ground the heater is grounded out so replace the heater.
There are two thermostats that can cause a Frigidaire dryer not to heat. One
is the hi-limit thermostat, which is located on the heater can. The other is the
operating thermostat located on the air duct housing.
To test the hi-limit thermostat you need to disconnect the wires from the
thermostat then test it with an ohmmeter. If the thermostat is open replace it.
Note that if this thermostat is bad you could have a clogged vent or a stuck
operating thermostat. So check the vent and it may not be a bad idea to replace
the operating thermostat as well.
The operating thermostat should have four wires; two on the outside and two
small wires in the middle. The two wires in the middle are for a heat
anticipator and this will not cause the dryer not to heat. The two outside wires
are the thermostat. To check the thermostat, disconnect the wires and test for
continuity across the wires. If it is open replace the thermostat.
On a typical Frigidaire dryer the only things left that will cause it not to heat are the timer and the motor. There is a switch in the motor that only allows the dryer to heat if the motor is running. These switches don’t fail very often and there is not safe and easy way to test them. Timers are very model specific so I cannot tell you how to diagnose timers.
