Heating, Air Conditioning, Fridge, HVAC/Fan


Jim, I do not have a yellow wire going to the relay. Here are the wires I have: a grey wire that is connected to the green stat wire, a black wire that goes to the sequencer and another black wire that goes to the blower, a red wire that goes to the blower, and a brown wire that goes to the sequencer.

Steve, there should be 6 wires on the relay. Check the numbers on the relay. Terminal #1 should go to green stat wire. #2 goes to seq, #3 goes to common on transformer ( this is the one I think is missing). #4 goes to Blk blower. #5 goes to seq and #6 goes to red blower.

Let me know what happens.

I can answer questions on gas or electric furnaces, ac units and heat pumps. I don't work on boilers,chillers,or home appliances.


I have been in the HVAC trade for over 35 years. For the past 15 years I have owned my own business. I am semi-retired so I can answer questions in a timely manner.

I attended trade school for 5 years on weekends and evenings. This was very hard to do, but well worth it!
