Kenmore Washer Won't Spin or Agitate in Clearwater: A Broken Motor Coupling
- Symptom
- The client said the washer wouldn't spin. It turned out it wasn't agitating either. The tub didn't move at all.
- Cause
- The motor coupling between the motor and the transmission had broken apart, so the motor could no longer turn the transmission.
- Fix
- Replaced the motor coupling on the spot with a genuine Whirlpool part we carry on the truck, then tested the washer through a cycle.
A client in Clearwater called about their Kenmore 90 Series top-load washer (model 110.20922990). The complaint was that it wouldn’t spin, but it was still washing. Once we checked it, it wasn’t doing either one. The tub and the agitator weren’t moving at all.
An old-school Kenmore
This is one of the older direct-drive Kenmores, and they’re tough machines. There are really just a couple of parts that tend to go on them. One is the lid switch. The other is the motor coupling, and that was the problem here.
To get to it, we took the cabinet off.
The coupling had fallen apart
On these washers the motor bolts straight onto the transmission, and the coupling is what connects the two. It’s two plastic drive forks with a rubber disc between them. It’s meant to be the weak link, so if the washer gets overloaded or something jams, the coupling breaks instead of the motor or the transmission. Once it breaks, the motor hums along but nothing turns.
This one was in pieces. Bits of rubber were scattered on the floor under the washer.
Half of the broken coupling was still on the transmission shaft.
A new coupling, on the spot
We always keep these couplings on the truck. It’s a small part, but these washers don’t run without it. We pulled the motor, put on a new genuine Whirlpool coupling (part 285753A) and bolted everything back together.
Here are the old pieces next to the new coupling.
Running again
We tested it, and the washer agitates and spins like it should. It’s an old machine, but a really good one, and with a fresh coupling it should keep going for a long time. If your older Kenmore or Whirlpool top-loader hums but won’t move, the coupling is the first thing we’d look at. More on our washer repairs.
FAQ
Why won't my old Kenmore washer spin or agitate?
On older direct-drive Kenmore and Whirlpool top-loaders, a broken motor coupling is one of the most common causes. When it fails, the motor runs but the tub and agitator don't move.
Is an old Kenmore washer worth repairing?
Often, yes. These older direct-drive models are simple and very reliable, and the usual failures, like the coupling or the lid switch, are small, inexpensive parts.
