noisy Beckett AFG

Beckett AFG developed a squealing/scraping noise when running, pre, post and when burner fired.

Likely causes?

    Something is wrong. Anything from rodent in the burner, to a pump, coupling, blower wheel or motor issue. What have you done to investigate?

    Nothing yet. My health/energy is not great these days. I planned, maybe, to disconnect the motor from the pump and briefly run it. If the noise continues, it's the motor, if not, likely the pump, blower wheel or something.

    I think it is pretty safe to try that.

    You could take out the pump screws and pull the pump out a couple of inches. Can probably leave the fuel line from the tank attached and disconnect the nozzle line. Check coupling. Just run the motor with the fan on it

    That sounds easier and more definative.

    How old is the burner? I wouldn’t touch it unless you've got a spare burner coupling. They don't play nice sometimes. You don't have a service agreement with anyone? Who does the annual maintenance?

    "scraping" sounds like the blower cage (wheel) is rubbing on something, and Yes, I have found dehydrated bats and mice in blower wheels. sometimes if you (with POWER OFF) lift the igniter you can spin the wheel by hand and see the problem. then loosen the motor bolts and deal with it. If you choose to pull the motor, find something, a small box, container etc. so you can rest the motor on it as not to hang it on the wire. Then while holding the motor steady apply power and see if the motor is noisy on its on.

    If you pull the motor out, the motor coupling is going to separate in one of four places. It is a tube with a coupler at each end, one that connects to the motor and one to the pump. as HVACNUT said, they can be a pain to get back together. Do it on a warm day so you have time to take the complete pump coupling, if required, to an HVAC supply an they will help you select the right part. You will probably have to cut the new coupler tube to length, by comparing it to the old tube. Easy to cut with w PVC cutter.

    While you have the moto and blower out, clean and hair and lint out of the housing. and clean the blower blades if needed.

    Good luck and let us know what you find.

    I've been doing it myself. Cleaning, filter, check pressure, etc.

    Probably 15 years old or so. I have a spare coupling, which I believe I ordered per the Beckett p/n.

    Guess I need to check I still have it before I do anything. Last time I changed one, years ago, it was reluctant to come out.
