Just got done removing my exhaust fan. If they are loud they are easily repairable by and electric motor shop. Basically all it was was a spun bearing. However the bearings are pressed onto the shaft.


Here are the directions:

Couple of tips. Remove the flue pipe first. Then disconnect the low limit at the switch and follow your wires and disconnect the fan wires.

Then you remove the screws. YOU NEVER TOUCH THE FAN until after you have lifted the entire plenum assembly out of the stove.

In the break down above you sit there and scratch your head how you are going to remove the four bolts to remove the top of the plenum from the fan housing. You cannot do this until you have removed the entire plenum assembly.

This is going to take you a few days to do. The fan shaft inside the plenum will be caked with carbon and the set screw that holds on the exhaust fan will be frozen. You want to take the whole plenum to the garage or what not and coat the entire shaft and set screws of both the exhaust fan and the cooling fan with liquid wrench or some other type product.

Be extremely careful of the aluminum cooling fan. These blades are extremely easy to bend and break.

Once you have coated it several times through out several days, take a cloth and a small wire brush and clean up the entire shaft and set screw. Find the correct allen wrench and see if you can turn the set screw out on the exhaust fan. Do not strip the set screw. It is very easy to strip. Very soft metal. If it does not break loose immediately you need to soak it in liquid wrench for a day or so more.

Once you have the exhaust fan free, now you can remove the bolts from the fan supports and take out the fan. Then try to carefully remove the aluminum cooling fan. BE CAREFUL with this fan.

Once that is removed take it into the shop and they will press off the bearings and put new ones on. Should cost you about $50. Voila, new fan a lot cheaper than the $158 replacement fan you get online.
