Performed furnace maintenance on 2007 Ducane heater. Upon arrival Mario stated that the system did not work early in the morning when he tried using the heater. Ran system before starting in system fired up properly and began to heat. Although during the maintenance I did find that the indoor blower motor had significant oil leakage and the single secondary motor control that powers the motor is significantly out of range rating 1.8 MFD which is too low. The motor is not moving enough air capacity across the heat exchanger which will result in it getting too hot as well. Recommend that surge protection is also installed To protect the circuitboard and any sensitive components from power surges that can be damaging. Ordered indoor blower motor and will be returning one part is in hand.
