How to reset Haier air conditioner without remote – step by step instructions

If you may have misplaced the remote or it has broken down, try these steps to reset your unit:

  1. Follow the power supply cable from your AC to its electrical outlet – the one it is plugged into. On the power cord plug, look for the buttons Reset and Testhaier air conditioner troubleshooting
  2. Next, Push the Reset button down if it has been raised. You may notice a green light appearing on some Haier air conditioner
  3. Lastly, turn your Haier air con on as you normally do.

Congratulations! The power supply has now been reset and the unit might start to operate without any further issues.

Important note

The power cord used in most Haier units features a current interrupter device.

In general, it is a good idea to test the device from time to time by first pressing the ‘TEST’ button then the ‘RESET’ while it is still plugged into an electrical outlet.

This can help keep some of the most common electrical and/or technical issues at bay.

Note that you should discontinue using the unit and reach out to a qualified service technician if you notice either the ‘TEST’ button failing to trip or the ‘RESET’ button refusing to stay engaged during the procedure.

The procedure is the same outlined above:

In short, simply press the ‘Reset’ button -on the plug case- to reset it and resume operation.

I should add that it is important to check if your AC is still plugged in- the plug could have come loose- before pressing the button.

In the event your portable unit still remains inoperable, you can proceed with the Haier air conditioner troubleshooting procedures we suggest below:

  • Test if the unit’s electrical wall receptacle has the proper voltage (you can also change to a new outlet).
  • Check the circuit breaker too- and reset, if necessary. Still on the circuit breaker, be sure to check if the fuse might need to be replaced as well.
  • Check if the AC is ‘OFF’- you, of course, don’t expect it to work while in ‘OFF’ mode.
  • Check if the unit’s warning light has come on and if so, drain the water. Sometimes this is the issue making the air conditioner malfunction.

This is mostly caused by disturbances such as electrical overloading, overheating, etc. in your home’s electrical current.

The remedy here is to test your electrical setup for any of these problems and repair as required.

Also, inspect the power supply cord for damage/pinching/aging – This is not easy to fix through repairs so be sure to replace it with a new power cord (check your manufacturer’s recommendations).

Proceed to try to reset it after repairing the problem.

  2. Next, grab a paper clip (or a similar object) and unfold it.
  3. Now use the unfolded paper clip to push your ‘Reset’ button.
  4. Allow the unit a few moments to complete the reset process.

The Filter reset pad feature automatically alerts you that the unit’s air filter needs to be cleaned.

In fact, the indicator light is programmed to come on after the unit runs for a set number of hours- for instance; window units will come on after 240 hours.

What you should do when this happens is clean the air filter thoroughly (check your Haier window air conditioner manual for instructions) then place it back.

The final step to make the light go off is pressing the Filter Reset pad / Haier air conditioner filter reset button (Haier air conditioner reset button for filter)
