Frigidaire gleq2152es0 dryer not getting hot enough. I've replaced the heating coil and cleaned out the vents. Thinking it could be one of the sensors. How to be sure as one is very expensive "High Limit Thermostat".
You will want to check the control thermistor and make sure that it is good. At room temperature the resistance should be 50K ohms. If not then the control thermistor would be faulty and need to be replaced. The part number for the control thermistor is 134587700.
My dryer had the control panel replaced about 3 months ago. Ran great. Now, when I turn on with a heat setting, it runs with no heat and stops and the lights start flashing. If I run it without heat it runs with no problem. What gives?
It sounds like there may be an error code popping up on the unit. If you access the tech sheet for the unit, it will tell you how to check diagnostic codes and what they mean. This will help with determining what is going on with the unit. More than likely you will need to check the thermostats and thermistor for the unit.
I have replaced the thermal limiter and the thermostat. My dryer is still not heating, but otherwise functions as it should. What should I do next?
There are 2 components other than the thermostats which would cause the heating element not to work. First is the motor and second the timer. The best option is to disconnect the power to the unit and access the heating element. Disconnect one wire that is going to the heating element, preferably the one on the thermostat side. Plug the unit back up and using a multimeter you will want to turn the dryer on and test for 120 vac at the terminal on the heater where the wire was disconnected. What this will do is eliminate the heater element itself and the motor. If there is 120 vac at this point then you know the heater is good and the motor is good because the other 120 vac coming through the thermostats is the timer side of the circuit. If there is not 120 vac at that point then you will want to test the other terminal on the heater and check for 120 vac. If there is not 120 vac then the motor would be bad and if there is 120 vac then the heater would be the issue.
