Before you call

Quick checks you can do safely

  • Thermostat set to COOL and 3+ degrees below room temp
  • Air filter — if it's gray and clogged, replace it and wait 30 min
  • Outdoor condenser fan — is it spinning?
  • Any ice visible on the line-set at the outdoor unit?
  • Breaker: check both the indoor air handler and outdoor condenser breakers
What it usually is

Most common causes in Tesoro

  • Dirty filter collapsed the evaporator coil into a block of ice
  • Capacitor failed — outdoor fan or compressor won't start
  • Low on refrigerant (usually a leak)
  • Condenser coil packed with dirt, grass, pet hair
  • Tripped float switch from a clogged condensate drain
When to stop troubleshooting and call: If the outdoor unit is silent and the breaker trips when you reset it, stop resetting it and call — that's an electrical fault.
