E22001504 Genuine Sleeve Bearing for Mitsubishi Electric Split System Air Conditioners, Fan Shaft Bearing

E22001504 is a genuine Mitsubishi Electric sleeve bearing for air conditioners. In split systems, a sleeve bearing like this typically supports the free end of the indoor unit's long cross-flow fan, opposite the motor. Mitsubishi Electric uses different bearings across its ranges, so check the number on your unit's parts list before ordering.

Mitsubishi Electric indoor unit squeaking?

A cross-flow fan runs almost the full width of the indoor unit, driven by a motor at one end and typically resting in a sleeve bearing held in a flexible mount at the other. Over time the bearing dries out or wears oval, and the fan starts to squeak, chirp or groan, often worst at start-up or on low speed. The fan can also begin to wobble, which makes it noisy and can lead to blades rubbing on the housing. Replacing a worn bearing early saves damage to the fan and motor.

Changing the sleeve bearing

Isolate the air conditioner before opening it, and have a licensed technician do the work if you're not confident. Reaching the bearing usually means removing the front panel, the drain pan and sometimes the fan itself. Note how the bearing sits in its mount, check the fan shaft for wear, and spin the fan by hand after reassembly to make sure it runs freely and quietly.

Questions about this part

Should I replace the bearing mount at the same time?

If the mount is hard, cracked or misshapen, yes, because a tired mount lets even a new bearing move and squeak. Check both parts while the unit is open and order them together to avoid a second strip-down.
