I was doing a little wiring yesterday and in the process shut down power to my Thermopride OL5-85 oil furnace a couple times via the circuit breaker in my panel. Now, the furnace isn't working.

If it helps there are some pictures of the wiring here (http://home.rochester.rr.com/retrieve/furnace.html).


Nothing is running. Not the fan, the pump, or the burner.
The reset button has not popped up and the light does not come on if I use the lever to manually pop the button.
I've double-checked that I'm getting power to the fan center.
I'm not getting 24V between any of the terminals on the thermostat terminal board
Power is being supplied to the fan limit control leads.
The fan does not come on when I set the fan limit control switch to manual.


Any suggestions as to how I can go about troubleshooting this would be greatly appreciated!

Thanks in advance,

Mark

At the fan center, did you check hot to gound or hot to neutral? Maybe you opened a neutral somewhere?

You got it. I'd checked to hot to ground. Neutral wire was loose in the panel.

Thanks!!!
