Englander 25-PDVC Shuts off after 2 to 6 hrs w/E1 code

[akyllonen]

I've had this issue with the stove shutting off (just stops w/E1 code) blower stops and augur stops. It starts up fine and runs at least 2 to 4 hrs (and as many as 6hrs) then just errors out. Issue started end of last season, and I just ran oil heat the rest of that season.

I put in a new burn pot gasket this year, as the old one was pretty much gone/destroyed. After that it ran fine for 2-3 weeks without the issue. Then the issue came back and will run on average ~4hrs before it errors out.

Thinking it may be a bad vacuum switch, and will be trying out jumpering that today, plus checking all the hoses/wiring as well. Door gasket seems good (did the dollar bill test). Not sure about the glass gasket as the corner where the ends come together seems a little frayed, but not sure if that's normal....

Any ideas what could be causing the stove to run 4hrs then just stop with the E1 errors?

Thanks!

When was the last time you did a COMPLETE cleaning....pull combustion/convection blower, clean vent, blow out every nook and cranny? Also, checking everything you stated is a good start. Clean the hole and hose out where the firebox vacuum switch goes to in the back of the firebox.

I did the yearly cleaning of the stove pipe, vent, etc at the beginning of the season. I have not pulled out the combustion/convection blower ever and I don't have a replacement gasket to try it right now...I'd have to order one.

As far as the back of the firebox goes, it looks like I have to remove the convection blower to get to it?

Looked at the vacuum switch going into the combustion blower and it doesn't seem quite 100% attached (pic below) not sure if when it heats up this could be the cause?

I had this problem, after cleaning as mentioned above the stove functioned as it should.

The should be another vacuum switch that goes to the back of the firebox.....

Did you have to remove the convection blower to get to this? Just trying to get an idea on how to get this cleaned out without tearing out unneeded parts

No....that's not the correct vacuum switch...there should be two of them in your stove, it's the other one. I posted a wiring diagram in the previous post

And yes, make sure the combustion vacuum hose is attached firmly too.....you can take that hose off too and make sure that hole is not clogged.

If you look to the right at the top of the burnpot, there is a hole. Make sure this is free of ash and unclogged....

OK, here's the other one. Do I need to take out the convection blower to get to it? I can't see how it is connected to the front of the stove and if it would just pull off

 

[slvrblkk]

No, you shouldnt have to

 

[slvrblkk]

Yes, I believe it just slides onto the front of the stove....no clips
