Robertshaw 780-715 24V AC Intermittent Pilot Ignition Control

I bought this controller to replace an SP-715A model on my 30 year old Magic Chef 100,000 BTU high efficiency furnace. I checked the Robertshaw website to be sure the new model was compatible with the older one. My furnace was working intermittently, then finally the ignitor stopped. For installation I simply moved the wires over one at a time from the old controller to the same position on the new controller. Some of my wires were different colours than stated on the new control. The position of the wire is more important than the colour. My original control had a wire to the flame sensor. The new controller does not need the flame sensor in my application. The new controller worked perfectly, my furnace is working again.

My furnace wasn't working. I called a tech and he said that the cause was the ignition module but he thought the heat exchanger had a leak and I needed a whole new HVAC. I found a youtube video which explained how to inspect a heat exchanger. I did it myself and found that it looked great, in fact it looked new. So, I ordered this module, along with a new CO detector to be safe, replaced it myself and all is well. I saved a lot of money and hope to get several more years out of my HVAC system.

I'm glad I could find this part , it was delivered promptly, it fit & works perfectly , totally happy.

Easy instal, furnace back up and running. Thank you
