On arrival, I spoke with homeowner, and he stated that the indoor blower motor would stay stuck on until he turned the breaker off at the panel for the air handler. I checked over the thermostat and wiring and I found that the indoor relay was stuck closed with constant power being delivered. I stripped back new low voltage wiring and secured wiring terminals at the run capacitor to ensure a proper common path for the high voltage electrical for the blower motor. Tested and verified operation. Everything is working at this time.
