E1 vac switch error code--

[Ed Churilla]

25-PDVC/55-SHP10, getting an E1 code. I did a bypass on the switch -- looking from the rear of the stove--it's the one on the right above the exhaust. It ran when the switch was disconnected and jumped. I see there are 2 switches listed-PU-VS and CU-VS. Which one is the one I need or are they the same? Also the vac tubing--is it a special kind? I used an automotive fuel line and replaced the original and it got brittle and I thinbk it might have contributed to the problem. Thx in advance--

also noticed that the feed auger does not work--is it because the switch is bypassed?

I pilled the switch and found it to be the PU-VS--Ordered one and also a foot of hi temp tubing. hope this cures the problem. Is there anything else I should be aware of? Any other testes I can do?

You said stove ran when switch was jumped,then you said it didn't,so I am confused.Anyway,check both switches,hoses,and clean out the inside of the nipples they go on to.

when the PU-VS switch was removed and the inputs jumped-the stove ran. When the switch was used it ran for 30 secs and shut down. What I noticed wasn't running was the feed auger when the switch was jumped. Pretti sure it's the switch--but am confused as to why the feed auger wasn't running when the switch was jumped.

It is my understanding either vac switch can shut down the top auger.The one that goes to the firebox is directly hooked to auger.The one going to exhaust fan runs through the control box,this one sets the E code. Anyone,feel free to correct me,if I am wrong. So perhaps your stove has a vacuum problem,dirty stove,restricted intake or exhaust,weak exhaust blower,bad gasket.

 

[Ed Churilla]

another question--the vac switches have 3 terminals on them and 2 leads going to them. Is there specific terminals the leads hook to? mine are like the attached pic--is there a correct way to attach the leads?

 

[Mt Bob]

Yes,and yes.Many people over the years have hooked them up wrong and compounded their problems.If you use the search feature,you probably can find the info here,I do not know off the top of my head.

This thread should help,as it describes how the switches work,even though switches have changed over the years.

Replacing Englander's 25-PDVC - 2 Vacuum Switches with a Heavier Metal switch.

Hello Working on an Englander 25-PDVC, the 25-PDV works the same. Symptom: The stove shuts down after about an hour. Auger stops and then fire dies out. Solution: Since the bladder in the vacuum switch is weak and can let go after the stove heats up, I am replacing the both switches with a...

If you "suck" on the port that makes it click then that the port you want. On the wire connections, there are 3- -- "C" is Common, " NO" is Normally Open, "NC" is Normally Closed. You want to connect to the "C" and the"NO"... Which means not running there is no connection, stove running and vacuum, connection is made.. And some stoves have 2 switches. combustion switch and firebox switch.. some (early ones I think) have just 1 , combustion switch... If I am incorrect someone correct me pleeze...

Thx for the info--explains it quite nicely. Did notice the NO & NC on the housing. And when I put a hose on the nipples and suck (lol)--I get nothing. Could this be the problem?

I'm assuming when you say nipples, you tried them both. If that's the case, then yes, it sounds like your vac switch is shot. For giggles, did you try and blow into both ports? Also, were you listening for a click or checking for continuity with an ohm meter?

blow or suck she's locked up on both nipples. there's continuity between C and NO no where else

thx again for your help

final results--vac switch replaced along with the combustion fan (it was pretty tight) it's running like a pup now

thx for all the help
