Furnace not working, 20 degrees outside

hrolsons Member Posts: 1
Our furnace is not working.  We have a company coming out tomorrow morning but it's 20 degrees and I'm afraid the pipes will freeze.  I've changed a furnace motor before.

The furnace comes on and spins and then after a few minutes makes a noise and the motor stops.  Control board flashes 3 times.  It is a Rheem furnace.

Do I need a new motor?  Any idea where to get one in Denver?

Thank You,

T. Derek Olson

    some where on the bottom door

    you will find a chart to tell you what the blinks mean . likely the inducer motor is shutting down and opening the pres. switch . see what the blinks are cluing for
