It is around 4-5 years old. It was working fine, then recently after completing the washing cycle and after a few minutes after the start of the dryer cycle. The dryer cycle shuts off without error (power to unit still on). We opened up the top and cleaned out all the lint caked on within the dryer duct and made sure lint trap off drain pump in front was cleaned. We started again and received a DHE error. We confirmed the dryer element was heating up fine. We also tested continuity to through the dryer thermostats and it had continuity. Also confirmed appropriate voltage over dryer element. We then took dryer duct fan off, turned it upside down and re-connected to make sure it was turning properly. It seemed to start and stop and it was also very hot so we thought there was a problem with the fan so we replaced the fan, and to be safe, also replaced the thermostat. Once that was done, a few seconds after the unit goes into the dry cycle, the cycle stops and shows a "PF" power failure error. We checked all connections we can find but everything looks connected correctly. We eye-balled the power board to see if there was any burn spots or anything else noticeable but nothing. We also eyeballed the power filter for the same but nothing looked out of the ordinary. The heating element was hot and confirmed the dryer fan duct was revolving, albeit for a short time. It seems that there is something tested after the heating element is started and the fan revolving, that is not working and which is telling the unit to shut off or "power failure". We had also unhooked the dryer thermistor to see if anything looked unusual but looked fine and re-connected. What else can I check and what part is likely to be at fault ? Since the wash cycle runs fine, I am hoping the power board is fine. Thanks

LE error code means the motor sensor has failed. The motor sensor is located in the back of unit inside the motor. You will need to order a replacement motor sensor from LG. You will need a 17 mm and 10 mm socket tools to do this job.

CD means cool down, press the pause start button, the door lock will open. It is an anti crease cycle. It mentions it in the owners manual, but it is hidden deep in the drying section.

This is a heater error. The heater element is open and not working. This is usually the problem but it could be other things also. You need a service call from an LG tech.

Thank you for your inquiry, friend!
I understand that your Frigidaire dryer has been providing you with an error code "PF". Typically "PF" stands for power failure this can happen if power is shut off during a cycle or the dryer receives insufficient power, which could be an issue with your power cord or control panel. Let's perform a reset on your dryer and you can do this by unplugging the power cord for ten minutes. If you need any additional assistance please feel free to reconnect. -Matt
