 I have a Rheem Furnace, about 15-20 years old. It was running fine and all of a sudden it I don't have any heat.

The sequence is as follows.

1. Put the thermostat in hold temp and set for 75 degrees Which I know if warmer than the house. There is three feet of snow outside!

2. Fan comes on. There is a little click then after about about 15-20 seconds,

another click and the igniter begins to glow. It glows real good and continues for

a brief while and then turns off. I never heard any gas valve open or something to that effect.

I checked the propane tank and it is at 80%. 

There is a large silver capacitor in the box that has some slight corrosion on the

tabs. I cleaned it well and replaced the wire connectors. What does this capacitor

do? Is it for the fan motor?
