for Hilliard, OH
I could not replicate the buzzing noise that the customer is experiencing coming from Carrier 80% 90,000 BTU Gas Furnace. Customer will try to capture on his phone. Previous tech said he heard an ordinary, normal noise coming from unit. All functioning properly at this time.
Upon arrival found thermostat not seated, removed, checked wires, re-seated. 72 in the home, set to 69 Set to 73, cycled heat. After thermostat reaches 73, ten more minutes and system shuts off. Per customer: problem (overshoot of set temperature) occurs most every day at 3am. System cycled off and didn’t show any improper or intermittent operation. Blower start winding strain, going to fail
