Possible Causes

Blocked air intake or exhaust by snow, Frozen LP regulator, Inadequate cold-weather kit (battery heater, oil heater) for climate, Ice accumulation on louvers

How to Fix / Troubleshooting

Safety first: Shut down the generator before clearing snow or ice. Beware of hot surfaces and moving parts.

  • Clear snow and ice: Remove buildup from around the enclosure, especially near intake and exhaust louvers.
  • Regulator protection: Ensure LP regulators are shielded from direct snow and ice. Thaw frozen regulators slowly; do not use open flame.
  • Cold-weather kit: In very cold climates, install Briggs & Stratton-approved cold-weather accessories (battery warmer, oil heater) to improve starting and operation.
  • Maintain clearance: Keep the recommended clearance around the unit year-round to prevent drift accumulation.
