SOURCE: replacing fan motor on a roof top unit, has a thru

If I have both blades and double ended motor, I just use a hacksaw and snip and cut the old one out. If inaccessable you can probably hammer the shaft from the other end, I can't recall if this one has a belly band or not but normally you can tap the shaft right through the armature.

That error code is "SY" and not "5Y" and it is for the evaporator sensor error. You will need to replace the sensor.Here is the part to order.

The part comes with a 365 day, any part, any reason return policy.

Access the evaporator assembly cover in the rear of the freezer section. In convertible units that can function either as refrigerators or freezers, and is located toward the bottom of the unit on the inner back wall -- if necessary, remove the two lower glass shelves and the crisper compartments.

Remove the screws securing the evaporator cover to the freezer wall, using a Phillips screwdriver.

Pull the evaporator cover away from the wall just enough to access the electrical connection behind the cover. Be careful not to damage the gaskets on either side of the evaporator cover. Reach behind the cover and disconnect the electrical connection from its wiring harness. Remove the evaporator cover from the freezer.

Remove the wires inside the exposed evaporator assembly from their retaining clips, then squeeze the quick-connect mechanism to detach the wires from the fan motor.

Remove the two hex-head screws that hold the fan motor mounting bracket to the back wall of the unit, using a 5/16-inch socket or nut driver.

Remove the two hex-head screws holding the fan motor to the mounting bracket, using the 5/16-inch socket or nut driver, then pull the fan blade off the motor shaft.

Examine the fan to make sure the blades are not damaged; if necessary, replace the fan itself as well as the motor. Slide the fan onto the motor shaft.

Attach the new motor to the mounting bracket, using the 5/16-inch socket or nut driver to secure the two hex-head screws.

Replace and tighten the two hex-head screws that hold the fan motor mounting bracket to the back wall of the unit, using the 5/16-inch socket or nut driver.

Reattach the the fan motor wires by clipping them back into the quick-connect mechanism, and set the wires back into their retaining clips in the same manner as they were attached.

Set the evaporator assembly cover back into place, then reach behind and connect the electrical connection into the wiring harness.

Secure the Phillips screws that hold the evaporator cover to the freezer wall.

Replace the shelves and crisper compartments if they were removed, then plug the refrigerator into its power source and verify proper operation.

Lights are on,but freezer and refrigerator controls are not, is there a reset, lost power for about two hours yesterday

the motherboard located behind a cover panel in the upper left hand corner of the unit is defective,it powers all aspects of the unit and is very sensitive to power surges,outages,blackouts,spikes,etc,you will need to replace it as there is no repairable parts to it,G.E, part # (WR55X10942) just unplug the unit,remove the cover,remove all harnesses to the board and replace(CAUTION) be sure to check both condensor and evaporator fan motors before replacing this board,because if one of these fan motors is bad,the new board will be destroyed immediately!!!

Maytag 27.3 cu ft model #MSD2756GEW freezer freezing refrigerator side not cooling

Check the air damper if it opens as you adjust the temperature control. If yes then check the freezer fan motor. First, disconnect the unit from the power source then remove the freezer shelving.

Loosen the two top screws and remove the two bottom evaporator cover mounting screws then grasp the bottom of the cover then carefully pull it forward and down to clear the upper flange.

Disconnect the evaporator fan motor leads. The wire leads are self-locking and it is important to squeeze the clip before pulling the leads off the terminals.

Remove the evaporator fan motor assembly and place it on a work surface. Connect the motor terminals to a service cord and plug the cord into the 120 VAC power source. If the motor fails to operate, it is defective and must be replaced.

Here's the service manual for further troubleshooting.

Howling noise from freezer fan, GE side-by-side

Replace the fan, Remove the evaporator cover in the back of freezer, and probably another cover for the fan. Unplug your refer first. Usually their are two screws holding the fan bracket to the wall or mount. disconnect the wires, and replace. Their is a newer model evap fan motor that does not have wiring terminals to disconnect, it is hard wired together and you have to practically remove everything in the freezer compartment to get at it. You have to cut wiring and splice the new fan motor in. Fairly tough job. Usually an evaporator fan motor bearing fails from the refer being moved or in storage for a few days at least with the doors closed and the unit unplugged. This allows all that moisture that was in the freezer to get into the metal parts of the fan motor and cause this problem. To prevent this always block the doors open if your refer is going to be off for a few days. This will allow the unit to dry out without damage. Sometimes it was just a bad motor from the factory. Good Luck, Appliance Specialists

Top of unit near fan is building up with ice, not

these units actually pretty easy to work on. first determine if the fan is or isn't working. with the door ajar, turn the thermostat up until the compressor comes on, (hopefully you don't catch it in the middle of a defrost cycle ha ha, it won't come on then. you could manually advance the timer, but save that for a "need to know" or if it matters) hold the door switch closed (pushed in) does the fan operate ?
If it doesn't, you'll likely need to replace it, outside the unlikely possibility a wire worked loose from the motor. Any service history on the unit recently ? you can visually inspect it by removing the evaporator cover/rear panel. Further to that, is the entire evaporator a block of ice ? you may have a defrost problem. I digress. you can ohm out the windings or connect a test cord to the motor to see if it runs. If the fan is working, you may have a system problem, typically you'll get a heavy frost pattern there, while little to no frost on the remaining evaporator coils if the unit is lo of refrigerant or a inefficient compressor (bad valves-not pumping sufficiently).
you can acces the fan motor by removing the rear panel inside the cabinet. BUT WAIT. you'll need a step ladder. you need to remove the top grill, first remove the screws. open the door, at the underside of the top lip around the cabinet you'll see a couple of phillips head screws, remove them. then you can take off the grill/cover. *NOTE; If you have custom wood panels on this panel it can be quite heavy, you can usually remove that by pushing the panel towards the ceiling and pulling towards you.(careful not to stretch the tension spring too much) access panel to the compressor/condensor area and unplug it from the wall. (or shut the breaker off to the unit, there are other ways, but I'll leave that to experienced techs like myself.)

rule out the motor problem and go from there. hope this helps.

good luck.

Yes , motor is bad . May not start , next time cuts off . The fan in the back by the compressor , is called the condensor fan motor . I would suggest cleaning the coils in front at the bottom , of dust , lint , pet hair , etc , before replaceing the fan motor . Also , clean the fan blade before reinstalling the motor .

Maytag mfd2561he bottom freezer

I had the same problem. I removed the rear panel of the freezer (4 screws), removed ice maker, and found the evaporator fan that blows cold air from the freezer to the refrigerator was bad. I removed old fan and began calling around for the replacement part. Turns out the original encased fan motor went bad because the motor was encased and condensation caused the motor to go bad. The new motor came with brackets and new unenclosed motor. Took 1 screw driver and about 1-2 hours of work. Make sure power and water is off before working on unit.
