Westinghouse Generator Error Code UV: How to Fix It

Q: What causes Westinghouse generator error code UV?

UV error occurs due to engine running too slow, faulty voltage regulator, worn carbon brushes, dirty air filter, low oil level, or damaged alternator windings. Engine speed problems are the most common cause.

Q: Can I still use my generator with UV error?

No, never use a generator showing UV error. Low voltage can damage sensitive electronics, cause motors to overheat, and create fire hazards. Resolve the issue before connecting any loads.

Q: How much does it cost to fix UV error on Westinghouse generator?

DIY repairs typically cost $20-100 for parts like air filters, oil, or carbon brushes. Professional repair costs $150-400 depending on whether you need voltage regulator replacement, carburetor adjustment, or alternator service.

Q: How do I reset Westinghouse generator after fixing UV error?

After repairs, start the generator and let it run for 5 minutes with no load. Check that voltage readings are stable at 115-125V. The error should clear automatically when proper voltage is detected.

Q: How often should I service my generator to prevent UV errors?

Perform maintenance every 100 hours or annually: change oil, replace air filter, inspect spark plug, clean carburetor, and check voltage output. Regular maintenance prevents most UV error causes.

Abstract

Westinghouse generator error code UV indicates output under-voltage, meaning your generator is producing less voltage than required for safe operation. This serious issue can damage connected appliances and indicates problems with the voltage regulator, engine speed, or internal components.
