I am a fairly new maintenance repair technician for an apartment complex in Beaumont TX. I am working on a Goodman electrical Hvac unit. When the resident has turned his heat on at night it wont shut off. He say's he like's the temp at 77*f. The mode is on heat and fan is on auto. He has had to turn the whole unit off on the breaker box. I have replaced the thermostat and heat sequencer from a working unit from another building, (Same model of course.) I tested the system once after the repair, and it kicked off for me as soon as the ambient temp reached 72* f, which is what I set thermostat on.reached the correct temperature. However he claims that at night when he sets the heat to 77* f it just keeps running. Please help!!!!!!
