Hello, This is my first time posting.
I have a Intertherm MGHA-056ABFC-05 furnace. The AC Relay box( has switches to switch from ac to heat) that was added to the furnace has went bad. It still controls the air conditioning but not the heat . I have been bypassing the relay box to use the heat. I tried looking for a replacement( Part # 7036150) but it looks long discontinued . What can I do or part can I use to replace this control box ? Everything else works fine. I will replace the furnace and ac eventually but I would like to keep using it until the ac finally dies.
Thanks,
Tom
