CGS Posted April 10, 2021 Report Share Posted April 10, 2021 I have a 21 yr old envrovent 1 .I'm expecting to have to replace elements later this year.I'm wondering if I should replace the motor while the kiln is apart. It's not making any weird noises. I'm just afraid in of a failure down the road . My kiln is 12 yrs old and has light - med.useage.Mostly fire to 04, but have done about 10 ^6 lately I've noticed the bottom is almost 1 cone cooler than the center and the top.

Do a visual exam. If the bearing doesn’t make noise and the rotor is in decent shape (maybe some light cleaning) and it spins freely and doesn’t vibrate excessively I would continue to use it. Set up correctly these fans only see maybe 110 degree air so they ought to last a long time. Link to comment Share on other sites More sharing options...
Denice Posted April 10, 2021 Report Share Posted April 10, 2021 My enviorvent motor wouldn't turn on one day, so my husband started taking the motor out to see what the model was. He was going to get a new one from Graingers, when he got it out he found a big wasp nest inside of it. He cleaned it out and it worked like new, I put a fine mesh screen in a new vent cover outside to keep the wasp out of it Link to comment Share on other sites More sharing options...
neilestrick Posted April 10, 2021 Report Share Posted April 10, 2021 Just so we're talking about the same thing, the Envirovent 1 sits directly beneath the kiln, mounted to a sheet metal plate that fits into the kiln stand, correct? If so, those models tend to die a lot faster than the Envirovent 2, because the motor on the 1 gets a lot of heat from the kiln. On the 2, the motor is not mounted under the kiln. I'm also not a big fan of the sheet metal plate- I've seen them warp and sit unevenly which causes the floor of the kiln to crack. If your current vent is running nicely- no rattles and rumbles, keep using it as long as the sheet metal is still flat and the kiln is sitting evenly. When the motor starts making a lot of noise, that means it's starting to wear out, however it can run noisily for a long time. Rather than replacing the motor, I would replace the whole thing with an Envirovent 2. Link to comment Share on other sites More sharing options...
BernieMcG Posted April 11, 2021 Report Share Posted April 11, 2021 We recently replaced our EnviroVent 1 with a new motor. Our previous motor wasn’t working, made noise and had a lot of rust on it. The replacement was easy and the same motor was reasonably priced. If and when this motor dies we will move to the EnviroVent 2 model. For now it is working well and draws heat away quickly. It’s very quiet too Link to comment Share on other sites More sharing options...
