What 3 flashes means

The pilot sparks and may light for up to 60 seconds, but the main valve won't open: low gas supply, a false flame signal, or a shorted or disconnected sensor or igniter lead.

Also shown as: IPI 3 flashes, depending on the model.

Likely causes

  • Low gas supply
  • Sensor or igniter lead problem

Safe first checks

  1. Make sure the gas supply is fully on and, for propane, the tank has fuel.

When to stop

Lead and sensor checks are for a qualified tech.
