Could I have burned out my furnace motor by turning the furnace on or off?
A few weeks ago, I turned off my furnace using the main ON-OFF switch next to the furnace. I then pulled out the filter, examined it, put it back, and then used the switch to turn the furnace back on.
A few hours later, I noticed that the house was getting very cold. The variable speed motor in the furnace had failed and had to be replaced.
Is it possible that I caused the failure by shutting off the furnace at the wrong moment?
