What E2 means
On GE portable air conditioners in the APCD, APWD, APSD, APXD, APLS and APLH series, E2 means the control read the refrigeration system sensor as abnormal. That sensor tells the control how the cooling coil is behaving, so with a bad reading the unit may cool poorly or shut down. Look for E2 on the display. This covers full model numbers such as the APCD10JALW.
Common causes of E2
- Refrigeration system sensor reading outside its normal range
- Sensor connection at the control
- Coil airflow restricted by a dirty filter
1. Note the code and what the unit was doing. 2. Clean the air filter and let it dry before putting it back. 3. Keep the intake and exhaust clear of curtains and furniture. 4. Keep the exhaust hose straight and attached at both ends.
- Whether a sensor is reading wrong or the coil is truly behaving badly stays unknown from the display
- We check the sensor and the coil temperature together, and quote any sealed-system work in writing first
Other Room Air Conditioner codes
What is the difference between E1 and E2 on a GE portable?
E1 points to the room temperature sensor, while E2 points to the refrigeration system sensor. They are two separate readings the control watches, so each leads us to a different part of the unit.
Can I keep running the unit with E2 showing?
We would not. If the control cannot read the refrigeration side properly, it cannot protect the unit, so leave it off until it has been checked rather than running it and hoping.
Does cleaning the filter help with E2?
A clean filter helps airflow and is a fair first step, but E2 is about a sensor reading. If the code comes back after a clean filter, the sensor circuit needs testing by a technician.
Still seeing E2?
A technician diagnoses it on site and gives you the price in writing before any work starts.
