What this part does

Supports the single-phase motor starting circuit so the JLC motor can develop starting torque.

Common signs of wear

Look for swelling, cracking, leakage, overheating, burnt odor, loose leads, damaged terminals, or failed electrical test values.

Possible symptoms

On applicable single-phase JLC hoists, possible signs include hesitation or failure to start, humming, weak starting torque, or a hoist that will not lift despite correct supply voltage.

Inspection / ordering tip

Disconnect and lock out power. Verify the problem is on an applicable single-phase model, inspect wiring and terminals, and test the starting component per qualified electrical-service procedures before replacement.
