Overload Indicator
Westinghouse Generator
Severity: ModerateWhat Does This Error Mean?
The Westinghouse Generator Overload Indicator lights up — and the generator may shut down or trip the circuit breaker — when the total wattage of connected appliances exceeds the unit's rated running capacity. Unplug all loads, reset the breaker, and restart the generator. Reconnect appliances one at a time, keeping the total below 80% of the rated running watts.
Affected Models
- Westinghouse WGen7500
- Westinghouse WGen9500
- Westinghouse WGen12000
- Westinghouse iGen4500
- Westinghouse WGen3600
Common Causes
- Too many appliances connected at once, exceeding running watt capacity
- A compressor-driven appliance drew heavy starting surge watts that spiked above the surge watt rating
- A short-circuit or failing appliance pulled excessive current on one outlet
- Running the generator at full load in hot conditions caused it to derate and trip
How to Fix It
-
Unplug all connected appliances before anything else
Do not attempt to reset the breaker with loads still attached. Disconnect every appliance from all outlets and the transfer switch (if used) before touching the breaker.
-
Press the circuit breaker reset button on the control panel
Westinghouse generators have a push-button circuit breaker on the front panel. Press it firmly until it clicks into the ON position. If it immediately trips again with no load, there may be an internal fault — contact Westinghouse support.
-
Restart the generator and verify it runs cleanly with no load
Start the generator and run it for 1–2 minutes with nothing connected. The Overload Indicator should be off. Listen for smooth, steady engine RPM — the engine should sound stable and not be hunting or surging.
-
Reconnect loads one at a time in order of wattage, smallest first
Add small loads first (lights, phone chargers, fans), then mid-range loads, and finally high-draw items like refrigerators or air conditioners. Pause 10–15 seconds between each addition to allow the engine to stabilize.
-
Calculate total load and stay below 80% of rated watts
Find the running watts for each appliance on its nameplate. Sum them all up. The total should not exceed 80% of your generator's rated running watts. For motor appliances, check the starting watts separately — the starting surge cannot exceed the generator's peak surge rating.
Frequently Asked Questions
What is the difference between running watts and surge watts on a Westinghouse generator?
Running watts (also called rated watts) is the continuous power the generator can safely deliver. Surge watts (starting or peak watts) is the brief spike the generator can handle for 1–2 seconds when a motor starts. Motors need 2–3x their running watts to start. The Westinghouse model number usually shows both figures — for example, WGen7500 delivers 7,500 running watts and 9,500 surge watts.
Does the Overload Indicator damage the Westinghouse generator?
A single overload that trips the protection is not harmful — the indicator and breaker are designed for this purpose. Running the generator continuously at overload, or bypassing the breaker, will cause overheating and permanent alternator winding damage over time.
