My heater core will not turn on and heat. I put a new thermal fuse but it still will not turn on, could it be the thermostat...
Answer Hello Joe. It is possible that the heater or a thermostat could be bad. You would need to use a meter and test the components for continuity. If they test out good then you will need to replace the timer.
The dryer seems to works just fine on all heat settings for a few minutes, but then the heat shuts off. The drum does continue to run.The heat doesn't appear to ever come back on unless I shut the dryer off and start it again. Then it will heat for a few more minutes and shut off. I have checked and cleaned all of the air flow paths inside and outside of the the dryer. I have replace "all" of the fuse/thermostat/cycling devices and the heating coil. Nothing has changed the behavior of the machine.
You will want to access the heater assembly and remove 1 wire from the heating element, preferably the one that does not connect to the thermostat. Turn the dryer on and give it a few minutes to recreate the issue. Once this has been done then test the wire that you disconnected from ground. If there is no voltage then the motor switch is faulty and would require a new motor. If there is 120 vac then test the wire that is connected to the heater for 120 vac. If there is not 120 vac then since the thermal fuse and high limit have been replaced then the timer would be the issue.
