Auger not working - Enviro EF3

Now about this: ":The flue has a cap with a kind of wire frame so the only thing that could fit down it is a bug"


And is that metal mesh clean as in fully open. Lots of folks have been shut down due to crap on the vent termination screen.

O.L is really OL, infinity on a digital meter, open circuit.
Is the switch supposed to sense vacuum, or pressure. If pressure, and it's a vacuum switch, or vice versa, it's not going to do the job.

Now where on the stove does the "vacuum line go to".

I have hardware mesh in my vent termination you can stick a pencil through it but it still gets gummed up with crap from the exhaust and can and does toss a #2 vacuum error when that happens.

Now that heat seeker has told us what the 0.L is namely open circuit and that 0.000 is closed circuit we might stand a chance of getting this thing running.

Did you clean the barb on the stove?

Sounds like a vacuum sensor is needed.

Is the hose going to the vacuum switch attached to the top port on the switch?

Now locate the Low limit sensor on the exhaust path (this is likely close to if not on the combustion blower cavity next to the combustion blower itself).

Remove the wires from it and take a Ohm reading it should be 0.L if you have a lighter or candle remove the sensor from the stove and with the probes attached pass the flame under the end of the sensor, the reading should change to 0.000 once the temperature exceeds 140 on that sensor be careful you are playing with fire. Once this checks out put it back together as it was..

This is the proof of fire system as well as how the convection blower gets turned on, once the priming charge has been delivered to the burn pot no more fuel will be delivered until this switch closes.

ETA: Should be two brown wires going to it.

OK, put it back the way it was and tell us what is currently jumper-ed on the stove?

The only thing that I want jumper-ed at this time is the vacuum switch wires and the switch should be connected to the meter probes and read 0.L

If it reads 0.L place a half handful of pellets in the burn pot and start the stove.

Please make certain that the flue is connected and that once the combustion blower starts the meter goes to 0.000 .

Pay attention also to the convection blower hopefully it will start up with the added pellets in the burn pot.

Gone to take care of the birds and to have a geezer nap.

If the vacuum switch had been connected the stove wouldn't have dropped a priming charge, you bypassed the vacuum switch so we still have a bit of a problem.

Did the pellet flow ever start back up?




I'm trying to see what on the stove is actually working and yes it is extremely rare for a vacuum switch to fail, they can and do but it is not the thing that normally happens.

The normal causes of a vacuum switch not closing somewhat in order are: Ash or other obstruction in the works including the barb and vacuum line (hose), open doors or ash drawers, bad or failing gaskets, loose, damaged or pinched vacuum line (hose) a failed, or failing combustion blower.

The instructions call for a second start sequence if there is still a flame when the stove starts shutdown if this shut down starts at the 15 minute mark after first starting the stove (this is the reason I had you place more pellets in the burn pot) evidently it is possible that your stove takes a couple of startups to get up to a run temperature.

There is also a 120 degree snap disk on the stove that will shut the stove off and another that will place the convection blower in high speed to help reduce a chance of the stove over-firing and yet another that detects an over-fire condition (high limit switch).

Ok guys- Enviro EF3 analog controls you turn dial a fire on, set it to desired heat hit the on button above the dial a fire
if the vacuum has set (closed) the auger control block will turn auger at the rate that the dial a fire is set to (I always set it to 12 oclock then it comes on 4 secs off 6-7 secs. It will feed as long as vacuum is set. The convex blower control on top is a rheostat also, turn to 12 or 1 oclock leave alone, it comes on. The POF sensor in exhaust path (above combustion blower) actually shuts the blowers off automatically after you turn the dial a fire all the way left and click (off). The combustion blower runs at one speed, its on or off. The EF3 lets yiou adjust the burn air/fuel mixture by continuous adjustment of the dial a fire and the air shutter adjustment on the left side facing (black ball handle comes thru stove side). There is a second sw on inner exhaust path that cuts off the ignitor once it reaches ignition (high exh temps). If you bypass vacuum and auger turns, only one thing can be wrong- either blockage of the exhaust path (99 percent of the time the problem) or bad vac switch or wiring (rare). A test I like to do- with exhaust pipe off, put your hand over the vent exhaust- you should feel cool air coming in from outside, if you don't find out why. It sounded like your vac switch worked (closed) when you were running it open into a room (I too say NEVER do that). Another thing to eliminate put power to your auger motor and let it run one revolution time it it should take about one minute (1RPM Motor), and see if pellets fall normally. EF3's are pretty bullet proof- I'd say a dirty exhaust vent is likely the culprit. Remember on that stove the dial a fire and convection blower controls are separate manual start controls but operate automatically once the start button is activated. Hope this helped good luck

Thank you stovelark.

Good deal there Peltz.
