I'm trying to make this old Magic Chef furnace work in my garage. I got it and the Fan Control Center was broken, laying inside unwired. I have no wiring diagram for this unit but the M# is G76-7502 C2-5. I need help wiring the fan control center and the fan limit switch to power. I bought a new White Rodgers Fan Control Center but am not sure which wires go where.
The fan control has 2 black wires coming out of the switch in the back that is normally open. And 2 red wires from a switch that is normally closed. Also, a black and a white wire that go to the transformer.
The fan limit switch has 3 wires going to it (red,blue and black). Any help repairing this mess would be appreciated.
Thanks, Brenny :confused:

Here is the wiring diagram from White-Rodgers' website.

http://www.white-rodgers.com/wrdhom/pdfs/instruction_sheets/0037-5786.pdf

This is a number that may or may not reflect the wiring diagram you need. However, if it is too different, go to http://white-rodgers.com and click on the contractors link, and you can begin searching for the model number of fan relay you bought.

If you replaced the relay, you can look that number up as well. Let us know how you make out...

Im connecting a 90113 to a LSi home furnace unit but other tech disconnected now they call me to installed but is a little confusing where everything goes... if someone is familiar with those units let me know...

I'm not familiar with that model #. Is it gas or oil fired?
