I have a Reznor gas heater with Honeywell V8200 gas

Customer Question
I have a Reznor...

I have a Reznor gas heater with Honeywell V8200 gas controls. It won't fire up. I have replaced the thermocouple and the thermostat. When I turn up the thermostat there is no sound at the unit.

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

Think larger problem than the thermostat. Pilot stays lit. Don't think it is power problem unless there is a fuse somewhere that is bad.

Contractor's Assistant: Do you plan on doing the work yourself?

Would like to but really don't know where to start beyond the thermocouple and thermostat.

Contractor's Assistant: Anything else we should know to help you best?

The book talks about a blocked vent switch but I haven't found the reset button. don't think the vent was blocked since nothing has changed with the vent. Is there a fuse somewhere?

I checked the red wires near the thermocouple goes into the gas control unit. If those are the gas valve wires there is no juice.
HVAC Technician: Gaztech, HVAC Technician replied 3 months ago

Check if transformer input has 120 volts in and 24 volts output

And check if high limit switch has opened contact.
