I bought this part for my 20 plus year old furnace recently. A friend came over and installed it within minutes and my furnace is up and running again! Thank you Amazon!

This relay was an exact fit and replacement for the one I removed from my Coleman Air Handler. My issue was that the blower fan would run continuously. The thermostat worked fine and the compressor would shut off once a certain temperature was reached BUT the blower fan continued to run instead of shutting off. The most likely culprit is a Fan Relay in a circumstance like that.Fixed my problem. No expensive 'service call' from my A/C guy. Took about 5 minutes to change out. Good to go!

This was one of several components that were replaced in a 30 year old furnace. It wasn't identical to the one it replaced, but a jumper across 2 terminals made it function identical to the old one. So far the furnace is working like it's supposed to.

I setup this relay on the normally closed terminals to cut power to my water pump for my house whenever my water-source heat pump turns on do I don't lose water to the furnace. It worked perfectly
