What to do if my Ecoer Heat Pump system cannot cool well?

  If your Ecoer Heat Pump isn't cooling effectively, several factors could be the cause. It might be due to high outside temperatures triggering normal protection controls to limit RPS, or a dirty air filter/blocked duct, which requires replacing the air filter and clearing any obstructions. Also, check for refrigerant leaks or insufficient refrigerant levels. In case refrigerant is blocked in the condenser coil, counterclockwise the TXV, ensuring the refrigerant coefficient is 0.6.

  If your Ecoer Heat Pump isn't heating effectively, there could be several reasons. If the outside temperature is too low and there's no third-party heat source, consider installing auxiliary heat for backup. Also, a dirty outdoor coil or one covered in heavy snow can cause this issue, so clean the outdoor coil. Ensure the air filter is clean; if dirty, replace it. Also, no micro channel coils shall be used for heat pump. Finally, check for refrigerant leaks or insufficient refrigerant levels.

How to fix Ecoer 2436 system that does not start but shows normally?
- C
  Courtney FloresAug 20, 2025
  If your Ecoer Heat Pump system isn't starting up but the digital display appears normal, it could be due to a lack of 24 VAC for the Y signal from the thermostat. Ensure that the Y/O/C wirings are correctly connected and the thermostat's cooling/heating setting temperature is appropriate. It could also be due to an incompatible thermostat; try using other traditional 24VAC thermostats.

  If your Ecoer Heat Pump system is operating in reverse mode, it's likely due to an incorrect O/B signal selection. To fix this, choose 'O' for cooling at the thermostat.

  If your Ecoer Heat Pump isn't cooling effectively, there might be several reasons. First, check and clean or replace the air filter if it's dirty. Ensure that there are no blockages at the indoor unit's outlet. It's possible the system is still in start-up control, or the outside temperature is too high which activates a protection control. Also, check for refrigerant leaks and ensure the refrigerant charge is adequate. Finally, make sure the TXV is properly adjusted counterclockwise, with a refrigerant coefficient of 0.6.

  Several factors can cause your Ecoer Heat Pump to not heat efficiently. A dirty air filter or a dirty outdoor condensing coil can restrict airflow. Clear any snow that may be covering the outdoor condensing unit. A lack of refrigerant due to leaks can also impact heating performance, so check the refrigerant level. In extremely cold winters, consider installing an auxiliary heater or using a dual-heating function for supplemental heat.

How to fix an Ecoer Heat Pump that doesn't start but the digital display is normal?
- I
  Isaiah GraySep 4, 2025
  If your Ecoer Heat Pump's digital display is normal but the system doesn't start, the issue might be a missing 24 VAC signal from the thermostat or an incompatible thermostat. Verify that the Y/O/C wirings are correctly connected and that the thermostat's cooling/heating setting temperature is appropriate. If problems persist, try using another type of 24 volts common thermostat.

What to do if Ecoer Heat Pump operates in reverse mode?
- K
  Kevin WallSep 7, 2025
  If your Ecoer Heat Pump is operating in reverse mode, it could be due to a wrong O/B signal selection from the thermostat or a damaged PCB. Try choosing the O signal from the thermostat. If that doesn't solve the problem, you may need to claim a new PCB to replace the existing one.
