No heat. Customer complained about blower motor noise and heat not working. Cycled fan to on. Found door switch to be shorting causing the power to cut out to the main board. Ohmed motor at 5 ohms. Amps were 7.4 on start up and 3.4 at run. Also found signs of lubricant leaking from motor. Due to age, condition and cost to repair, second opinion set up for today.
