System locking out with no apparent reason. After checking multiple parts including but not limited to contactor, pressure switches, and incoming low and high voltage, control board is found to be faulty. 60uf capacitor is also reading low at 55uf. Replaced capacitor for testing to see if that was the issue with no improvement. Called for parts and availability from supply house with no answer. Left a voice mail but will have to call back for quoting. System is non operational at this time. Fan will still operate and can be used but cooling nor geothermal heating will operate.
