Westinghouse Generator Error Code OV: How to Fix It

Q: What causes Westinghouse generator OV error code?

OV error is typically caused by a faulty voltage regulator, incorrect engine RPM, bad capacitor, loose electrical connections, or in rare cases, damaged alternator windings. The voltage regulator failure is the most common cause.

Q: Is it safe to use my generator when it shows OV error?

No, never use a generator showing OV error. High voltage output can permanently damage connected appliances, electronics, and pose fire hazards. The safety system shuts down the generator to protect equipment.

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

DIY repairs typically cost $30-150 for parts (voltage regulator $25-100, capacitor $15-50). Professional repair costs $150-400 including labor. Voltage regulator replacement is the most common and affordable fix.

Q: Can I reset Westinghouse generator OV error code?

OV error will clear automatically once the underlying voltage problem is fixed. There's no manual reset - you must repair the cause (usually voltage regulator) for the error to stop appearing.

Q: How do I prevent OV error from happening again?

Perform regular maintenance including cleaning connections, checking engine RPM annually, replacing capacitor every 3-5 years, and keeping the generator clean and dry. Avoid overloading and ensure proper ventilation during operation.

Abstract

Westinghouse generator error code OV indicates that your generator is producing dangerously high voltage output, typically above 130-135 volts instead of the normal 120V. This safety feature shuts down the generator to protect connected appliances from damage.
