I was wondering if I could get installation instructions for part #AP4359310
Answer Hello Sarah,
I will try to get close without the model number of your unit. Remove the power supply to the unit and remove the main top by removing the two or more screws near the top of the unit from the rear. Remove the screws holding the board bracket in position. Remove the screw/screws holding the board to the metal bracket. At this point, take several pictures from several directions to aid in the new part installation. Remove the wiring connectors and connect to the new board. (Do this one wire/connector at a time so all of the wires remain connected at all times). This will even more prevent re-assembly issues. Re-assemble in the reverse order.
The heating element never cycles off runs all of the time, until the thermal fuse blows. Can this be a board?????
This issue would most likely be caused by a bad cycling thermostat and/or high limit thermostat. You will also want to check to make sure that the venting from the blower wheel to the outside of the home is clean and clear with no restrictions.
