Quad Sante fe comb blower dying?

Comb. fan is suppose to run after conv fan shuts off, to clear all hot coals. If you don't have some bad wire connections,or a dirty fan, I would say the fan is on its way out, or the control box. TIme to call the dealer. Esp. if you are still under warranty. From the date, time is running out. kap

How is the warranty done?

You may be able to get an aftermarket motor much less costly.

I have heard conflicting stories on the aftermarket ones. And they don't just screw back on with their holes. kap

At the bottom left of the page, click on OEM conversion here. There's the entire housing for $255, maybe you need that, or not...

Most of the blowers are shipped with the housing to protect the blower. kap

That behavior is usually the bearings have worn and dried out. A short term fix is to get some lubricant onto the bearings. They may run for a few weeks, but that is the beginning of the end for them.
The motor is what has failed, not the blower. Removing the fan from the motor shaft is a real PITA, but it can be done. Buying just the motor will be less expensive than buying the whole blower assembly, but it is a lot more work and there is risk of the fan being damaged.
Zoro has good prices on both the blower assemblies and motors.

In 30 years, I've seen very few successful attempts at seperating the CA blower wheel from the armature shaft, very few. Most times either the set screw strips out or because the hub welds itself to the armature shaft from the intense heat, when the owner tries to remove it (blower wheel), the wheel comes apart.

Better option is to bite the bullet and get the complete CA blower assembly and starting to do some preventative maintenance to it, like oiling the bearings every few months and keeping the dust off the motor.

Myself, I have what I call a maintenance fund and every year I put a couple hundred in it toward replacement parts. That way it don't hurt so bad because mechanics wear out over time, less time if they are neglected.

The housing is fine, seems wasteful to buy another.

In the end, unless you are extremely lucky, you will.

I too, have an abundant supply of spare parts, that I have gotten a little at a time. It's a good feeling knowing you can replace most anything on the stove if it goes down. kap

Some of the aftermarket ones have been known to have different cfm speed, and don't hook up without having to drill holes different. The Quad fans do have sealed bearings but getting a little oil on the shafts where they go into bearings brings some life back to the fans. Some longer then others. I had a friend that his exhaust fan was squealing. He sprayed some WD40 on it and it quieted down. That was 3 years ago. Not everyone will be that lucky. kap

Generically speaking, I'd take the fan wheel off the new one (when you get it) and apply some copper never-sieze to the threads that the setscrew engages and the hub and reassemble the fan to the armature shaft. That won't guarantee it will come apart later on, but it gives you a better chance.

Again, my general suggestion to anyone with a pellet/corn stove is have a replacement part fund and 'deposit' a hundred fifty or so every year so when something breaks or wears out (and it will), it don't hurt to replace it. It's gonna break at some point. you just don't know when.
