Why won't my Westinghouse WGen12000 Portable Generator start or remain running?

  Shawna GreenAug 15, 2025
  There are several reasons why your generator might not start. Ensure the fuel shutoff valve is in the ON position and that the generator has gasoline. Inspect and clean the fuel delivery passages to ensure there are no obstructions. If your model has an electric start, check the battery output and charge it if necessary. Also, check and clean the air filter, and verify the oil level is sufficient. Make sure the spark plug boot is fully engaged with the spark plug tip and that the spark plug is not faulty. Finally, drain any stale fuel and replace it with fresh fuel. If none of these steps work, the generator might have a fault and should be taken to an authorized service dealer.

  Daniel ChristianAug 18, 2025
  If your Westinghouse Portable Generator starts and then shuts down, it could be due to several reasons. First, check if you are out of fuel and refuel if necessary. Also, check the engine oil level and ensure it is correct. A dirty air filter can also cause this issue, so clean it. If the fuel is contaminated, drain the fuel tank and refuel with fresh gasoline.

What to do if my Westinghouse WGen12000 has no power at AC receptacles?
- C
  Casey McintoshAug 21, 2025
  If there is no power at the AC receptacles of your Westinghouse Portable Generator, several issues could be the cause. If the OUTPUT READY LED is OFF and the OVERLOAD LED is ON, check the AC load and the air inlet, then stop and restart the engine. Another possibility is that the AC circuit breaker(s) have tripped, so check the AC loads and reset the circuit breaker(s). Also, a faulty power tool or appliance can cause this issue, so replace or repair the tool or appliance, then stop and restart the engine.

Why does my Westinghouse WGen12000 Portable Generator engine lack power?
- C
  Caitlin YoungAug 26, 2025
  If your Westinghouse Portable Generator engine lacks power, it could be due to a restricted air filter. Clean or replace the air filter. Another cause could be bad fuel; if the generator was stored without treating or draining gasoline, or refueled with bad gasoline, drain the fuel tank and refuel with fresh gasoline.

How to fix a Westinghouse WGen12000 Portable Generator remote start system that is not working?
- L
  Lisa OrozcoAug 28, 2025
  If the remote start system isn't working, first replace the batteries in the key fob. Then, ensure you are within 100 feet of the generator. If it still doesn't work, the remote start key fob may need to be programmed to the generator.

  rebeccagonzalezAug 31, 2025
  If the engine of your Westinghouse Portable Generator runs rough or bogs when a load is applied, it could be due to a dirty air filter, so you should clean it. The generator might also be overloaded, so unplug some devices. A faulty power tool or appliance could also be the cause; try replacing or repairing the tool or appliance, then stop and restart the engine.

  First, reset the circuit breakers and check for any overload condition. Then, verify that the power cord plug connector is firmly engaged in the generator's outlet, rotating it 1/4 turn clockwise if using the 240V outlet. If the issue persists, replace the power cord or try connecting a known good appliance to rule out a faulty appliance. Also, check if the GFCI outlet has tripped and switch it to the operating position. If none of these steps work, the generator might have a fault and should be taken to an authorized service dealer.

What to do if Westinghouse WGen12000 Portable Generator suddenly stops running?
- B
  Brandy ConleySep 7, 2025
  If your generator suddenly stops, start by checking the fuel level and adding fuel if necessary. Also, check the oil level, as the low oil shut down switch may have stopped the engine. Add oil if needed. If those aren't the issue, restart the generator and reduce the load. If the issue continues, the generator might have a fault and should be taken to an authorized service dealer.

Why does my Westinghouse WGen12000 engine run erratically?
- A
  April GriffithSep 12, 2025
  An erratic engine speed can be caused by a dirty air filter, so cleaning the air filter is a good first step. Also, changes in engine speed may occur as loads cycle on and off, which is normal. If the issue persists, the generator might have a fault and should be taken to an authorized service dealer.
