Hello members of Hearth.com,
I am narrowing down a problem with my 5 year old Drolet ECO-45 pellet stove, but I'm at a point where I could use some help. I've almost got it down to the Vacuum Air Pressure Switch Sensor (part number 44029).
Main symptom: convection fan does not come on after the ignition cycle does its thing. The fan has been tested (bypassed) and is fine.
We narrowed it down to the air pressure sensor that's mounted to the inside rear wall of the stove. The stove functions as expected when this sensor is bypassed (the wires are connected directly, without going through the sensor). It ran for a few hours last night like this. So we almost have it, but there's one more question: is the sensor bad, or is it not getting air?
I came across a couple write-ups where people were testing the rubber hose that leads from the combex motor to the pressure sensor by detaching it from the sensor and blowing into it. I did this, and I can blow through it, but I have to put some force to my breath. It's not easy like blowing through a straw. The opening is smaller than a straw, so maybe this is normal but it's hard to gauge (and describe). The stove was off when I did this, by the way.
The area where it connects to the motor is very cramped, and while I could pull it off easily, getting it back on is going to be a serious challenge, so I don't want to do it unless it's really necessary.
I also read in a couple places that a certain sensor on the ECO-45 was bad in many stoves in a certain serial number range, but I wasn't able to find more info on this (which sensor, and what range). But I'd rather not buy a new sensor just yet until I get this hose figured out.
If anyone can share some thoughts on the hose, I'd really appreciate it. I don't feel comfortable running the stove with a sensor bypassed, and it's been a cold few nights.
Thank you in advance!
