I wish I had more concrete info for you, but it without the wiring diagram and the part numbers, there’s no way to verify via long-distance. I’m not sure where in PA Mount Wolf is located, but I have a Master Certified technician in Eastern PA who might be able to help. Give Ron Donachie a call and see if he can make a service call for you. Here’s his contact info:
