Pellets only drop of I unplug and plug back in stove

[AimeeL]

Hello. I have a heatilator ecochoice. Recently pellets won’t drop on their own. Stove starts up, but pellets don’t drop.
I do not believe it is a clog because if I unplug the stove and then plug it back in it runs fine for a cycle.

Try jumping the vacuum switch. If it works normal then check you vac hose and ports to make sure they are clear.

update: I replaced the vacuum switch and hose, replaced snap disk #3. Stove worked great for about 5 days, but then went back to not dropping pellets unless I unplugged stove to reset it. Any other ideas?
