What Does Error LO Mean?

The Hotpoint air conditioner error code 'LO' indicates a low temperature condition, typically signaling that the ambient temperature is below the measurable range or a faulty temperature sensor is misreading data. This can prevent the unit from cooling effectively, causing it to blow warm air. Check the sensor placement and ensure it's not exposed to drafts or extreme cold.

Common Symptoms:

  • Display shows 'LO' instead of a numeric temperature.
  • Air conditioner may not start normal cooling operation when 'LO' is displayed.

Possible Causes

  • Actual ambient temperature below minimum measurable range or below the unit’s setpoint range (medium)
  • Faulty or mislocated temperature/ambient sensor reading abnormally low (medium)

How to Fix Error LO

DIY Fix Check environment and sensor placement

  1. Verify the room temperature is within normal operating range (not extremely cold).
  2. Check if the temperature sensor is exposed to drafts or placed near open windows/doors.
  3. Ensure nothing is blocking or artificially cooling the sensor area.

Technician Only Inspect and test temperature sensor

  1. Power off and safely access the unit’s temperature/ambient sensor.
  2. Test sensor resistance/continuity against manufacturer specifications.
  3. Replace sensor if readings are out of expected range or if physical damage is evident.

Parts needed: ambient temperature sensor

🛑 When to Call a Pro:
  • If the error persists after verifying ambient conditions and sensor placement.
  • If the sensor tests outside specifications or shows intermittent readings.
