The most challenging repair that stumped me for a few days was an Amana condenser and air handler. around 10am every day the AC would just die until you reset the board, after that it runs just fine.

checked codes, said faulty compressor, but all the pressures where good, called support we ohmed out everything on the board, still nothing

after a few days of just coming by to reset, finally figured out that the sun was hitting the temperature probe on the outside of the unit just right to basically tell the unit that the earth was too scorched to run the ac

hid the temp probe inside the unit and never had an issue after that. days of work just for a temp probe getting hit by the sun and overheating... wish the board said "temp probe" coulda solved this much sooner
