My step father just had an Englander 25 pdvp given to him. Cleaned it all out. Got it piped correctly. It starts in S U mode. This unit does not have an igniter. The exhaust fan and top auger will cycle on and off for about 5-7 seconds. Shut off. Will do that 4 or 5 times. Then they cycle for 1-2 seconds. Then nothing. Over and over.
