My heat is not working, and the repairman said it was the motor. Does anyone know where I can buy 1 for cheap?

Sure, open the yellow pages and look for HVAC supplies - you are looking for a small mom-and-pop store in the area. Then call and tell them the unit you have - manufacturer and model number and they can tell you how much for the motor.

I think your effort is doomed. But here is how to try it. Take the brand name and part number off the existing motor. Look at a web site for that brand motor and also call some local electrical motor distributors. Get a quote for how much you can buy the motor for. Also take a look at that motor and see if you can tell how it is mechanically attached and how many wires are connected from the motor (usually two plus ground unless it is a two speed blower motor).

If you are sure you can accomplish that with your friend's help and presence there then get the motor and mount and rewire it to save that money. If you are not positive you can do that safely don't even start the project. All your pipes will freeze during the next cold snap if you start the project and can't complete it without either doing damage or killing yourself.

I seriously doubt that friend's estimates. I think they are low-balls you will never get. Tell him if it doesn't work out you are going to have to move into his house till springtime. That should give him a dose of realism.

The value is in the know-how. After you have frozen your buns long enough and can't find the right size motor, you will call back the repairman to fix it.

Replacing a motor like that is relatively easy. You just need the exact replacement for your system. Many times you may have to remove a bracket from the old motror and bolt it to the new one, and then re-attach the bracket the same way you took it out.

if it is a blower motor they are very simple to repair usually held in place by four to eight screws pull the blower out and there is a shaft on the back there is a bolt that holds it in place usually you can shake it free, but putting it back in just be careful you have enough clearance because if you get it to close to the blower you might warp your blower causing a whistling or you might burn up your new motor. finding one should be easy, look for a universal motor they are about fifty dollars cheaper make sure it is the right size the numbers on the motor will help

There are how Habitat for Humnanity stores open, I don't know how many stores or where but it might be worth while to check if there is one in your area. They have all kinds of stuff for sale for your house, some donated by local home improvement stores, contractors and builders, etc. Some of it is leftover construction material, some just overstock, and they sell it for really low prices, just pennies on the dollar, really..Don't know if you could find a motor there, but maybe. The one in our town has all kinds of HVAC stuff.

I guess I'd have to know if it was a belt drive motor or a direct drive motor, hp, rpm.........how many speeds......... gonna need a new capacitor for most direct drive motors also. Everything on a furnace is not under a 100 bucks in cost......... try replacing a combustion fan assembly for under a 100 bucks............

Yes, you can replace the fan motor yourself and save a lot of money. Very simple to do...
