Have a Rheem Criterion Furnace - blower motor will not come

Customer Question

Hi have a Rheem Criterion Furnace - blower motor will not come on. Tried fan only on thermostat and Ac unit also. Wondering if it is the board or the blower motor itself. Is there a way to determine which one it tis?

This will be either a bad control board or bad motor.We can determine which one if you have a volt meter for troubleshooting.Let me now if you have a meter.

You can get an inexpensive one at Walmart for about 15 bucks if you would like to troubleshoot and I would be happy to guide you.

Excellent. Then look just above burners on inside right or left panel and give me model so I can pull a manual and see the exact board and wiring diagram.It will be something like RGPH07EAUER or similar.

Then tell me how many wires go from blower to board, I can then guide you accurately in telling you where we want to check for voltage in each mode.

Look forward to helping you.
