Updated · by Aurora Star Tech Inc.

Clearing lockouts on a Rheem furnace: Soft lockouts (five-minute pressure switch, one-hour ignition/flame) and hard lockouts clear differently.

How to fix clearing lockouts: step by step

  1. Any lockout clears when the cause is fixed and power is cycled off and on.
  2. Soft lockout only: remove the heat call for more than 2 but less than 20 seconds.
  3. Hard lockout from a dead blower (61 four times in one call) clears if you cycle the heat call; a 93 hard lockout does not.
  4. During lockout, cooling and continuous fan still run but the display shows the lockout code instead of C or F.
Safety: Gas, electrical and refrigerant work must be done by a licensed technician. Turn off power and gas before servicing, never bypass a safety control, and always follow the manufacturer's manual for your exact model.
