i have an older sears 600 wall furnace. the problem is the burner kicks on then the blower like normal but after 30 seconds to a minute the blower shuts off while the burner never goes off. the fan keeps going on and off and never stays on for anything longer than a minute.
Optional Information: Make : sears Model : 600
Hello
This is a bad blower switch. It activates with heat for on/off temperature.
The switch is kicking on, then cooling a bit and turning off, then heats up and turns on again.
.
do you know where i can purchase one or have a picture of one so i can remove and replace?
Yours will be similiar to the one at this link.
Except your is not adjustable and the one pictured is. The adjustable lets you pick how fast you want it to kick on and then how long to run to cool the Furnace. see here
