Working exhaust fan Dayton 8M209. Hightpitch sound at high speeds

It worked fine for years (summer almost continuous use) Then went on working but with this loud high pitch noise. Graingers told me it means bearings problem. I see that I was supposed to add oil every two years. Never did and I wonder if I should try that before replacing motor

    Dayton 8M209 is not a heater fan, it is a window exhaust fan to move out hot air from garage to outside

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

SOURCE: Blower motor or resistor?

If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.

SOURCE: Dishwasher Making Loud High Pitched Noise.

A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.

Why my driver fan is working onl Hi level only


I guess you mean inside the cars heater fan the switches contacts went bad if you mean the engine fan I don't know what kind of car this is but there are fans that have a low speed & a high speed and if the relay went for low speed you would only get high speed but because of the high weather temperatures and where you are could be the reason the engine is calling for high speed all the time I'm trying the best I can for the limited information you have given

120hp force outboard cooling & exhaust


it is possible that the length of the leg is insufficient and the pump pick up holes are in the clean area behind the keel of the boat when at speed and on the plane
if it is a deep V boat and you have a standard length leg for the outboard , that would be worth checking

I dont understand how the intake and exaust features work, and the temp guages work? i just use max speed ,


mcdevito75 here, The intake and exhaust feature is simply a reversal of the fan motor or motors. On intake all the air is being brought in from the outside to inside your home, this is fine for the spring and fall, but in the summer time when it"s both hot outside and inside your home you"d want to use the exhaust feature to get the hot air out of your home and let fresh air from the outside in. The temperature settings, unless your fan is actually an air conditioner and not a window fan are the fan motor speeds, you set these speeds to suit yourself. If this unit is an air conditioner you can set the teperature aorund 65 degrees or approx. Half way thur the blue sash on the knob or half way between cool and cooler depending on how your teperature settings read.

I've got a Dayton 3E369 Unit heater. The electric


Sounds like it has a bad fan switch wich is no more than a small circular bi-metal switch that expands when heated closing a switch. Get a parts breakdown off the net. I am sure you could find the switch in your area and replace it yourself.

Fan will not run on high. Compressor runs fine but the fan will not run on high. Works fine on low and med.


It's the mode switch contactors for the high setting just overview the wiring of the high cool or high fan contactors if it's not there check all leads for the high fan or high cool circuitry.

need to check you fan wires, some have differant colors on the moter for the differant speeds, you may need to change the fan speed by unplugging one of the wires and replacing it with another. hopefully you still have the manuel , check with it first!!!
