Test the Exhaust Blower Fan 25 Pvdc

So I got a used 25 Pvdc and installed it. All has been well until yesterday morning I wake to notice the E-1 Code. Fire it up again last night and E-2 then E-1 Code. Not entirely sure the exhaust fan is working as the flame looks less "constant" and more "flickery." but to be honest this stove has never been quiet so it not as easy to tell as I'd thought.

How do I test the exhaust fan?? Must be a jumper wire or something but don't want to randomly hook up wires.

I did a search as I know there is a thread on it somewhere but finding it is tough. Kind of a good problem as this forum has sooooo much info on it


PS I have already printed out the wiring diagram.

There is a test mode that allows you to turn functions on and off from the control panel. Instructions are on the ESW website.

I am not sure that you could get it to ignite if the blower wasn't working, in fact it wouldn't feed pellets if there wasn't enough vacuum to satisfy the switch. I believe that E-1 indicates a vacuum loss. I had this happen intermittently when the tube running to the switch was leaky. E-2 indicates failure to start and could be a result of the E-1.

wow thats too easy! thanks
