Diagnosed and serviced mobile home furnace that was reportedly shutting off in auto mode but working in manual mode. System was functioning properly during inspection, but discovered and replaced weak capacitor as preventative measure. Customer also reported gas odor from stove - soap tested fittings and found no leaks in the flex line, advised issue likely within stove itself which is outside our service scope. Customer was informed that waste oil burner in shop requires specialized service not offered by our company.
