Hello, What's going on with the unit I have is when the blower quits blowing air through the ducts I still here a noticeable hum coming through the ducts like something is not shutting down completely. It keeps humming until the blower kicks back on. The hum never stops. I'm good with fixing it, problem I have is trouble shooting. Im not sure if its a fan switch or something to do with the thermostat. I do not know the age of the unit as it was it the house when I bought it. I will provide any additional info that is required. Thanks for assisting me, my children and wallet, we greatly appreciate.:help:

I have a Pro Fusion 7500 watt electric garage heater (p/n EH-4604B). I want to wire in a SSR with a transformer to control the power to the heater with an external thermostat. Problem is the amp draw of the heater is 31.3 on 240 volts. Does anyone know the part number of a Solid State Relay with a built in transformer that can handle 31.3 amps? Or does anyone have a suggestion on how to do wire this heater so that I can use it with an external thermostat? I've included links to the wiring diagrams of the heater and to a SSR made by aube technologies that is an example of what I'm looking for. Thanks for any thoughts or ideas.
