What Evaporator sensor error means
On GE built-in room air conditioners in the AJCQ and AKCQ series, an evaporator sensor error means the evaporator temperature sensor is reading wrong. The evaporator is the cold coil inside the unit, and the control uses this sensor to protect it. In the printed troubleshooting list the code appears only as a dot, so we describe it by its meaning. Full model numbers include the AJCQ10ACH and the AKCQ10ACJ. Cooling may be weak or stop.
Common causes of Evaporator sensor error
- Evaporator temperature sensor reading outside its normal range
- Sensor connection at the control
- Coil iced up from low airflow
1. Unplug the unit, wait a moment and plug it back in. 2. Check that the air filter is clean and the room-side grille is not blocked by curtains or furniture. 3. Try cooling again for a few minutes. 4. If the error repeats, leave the unit off and call for service.
- Whether the sensor reads wrong or the coil is really icing stays unknown from the display
- We check the sensor and the condition of the coil, then give you a written price
Other Room Air Conditioner codes
What is the evaporator sensor on my air conditioner?
It is the sensor that reads the temperature of the cold coil inside the unit. The control uses that reading to protect the coil and to manage how cooling cycles on and off.
Why is the code just a dot in my manual?
The printed list shows it as a dot, so the exact characters are not given. We do not guess at them and describe the error by its meaning instead.
Can a dirty filter cause this error?
A clogged filter can let the coil get too cold and may contribute. Cleaning it is a good first step, but a repeat of the error means the sensor itself should be tested.

A technician diagnoses it on site and gives you the price in writing before any work starts.
