Haier Portable Air Conditioner Not Working? (7 Common Haier Portable Air Conditioner Problems for Troubleshooting)

Consider the seven problems shared below and their troubleshooting if your Haier portable air conditioner is not working:

1. Haier Portable Air Conditioner Not Turning On

One of the issues below is the reason your portable air conditioner is not turning on:

  • Power loss – It’s essential to check if there is a power loss. If it is, then that’s the reason your portable AC won’t turn on, and so you must wait for its restoration. 

  • Unplugged or loose power plug – Check the plug to ensure it’s not just plugged in and turned on but firmly plugged in. If not, the AC won’t turn on.

  • Defective power socket – A faulty socket will also prevent the AC from turning on. Try plugging in another device and if it doesn’t power on, replace the socket.

  • Tripped GFI/GFCI reset button – This reset button on the power cable may trip during a power surge. So, check it and reset it if it’s OFF. 

  • Tripped circuit breaker – Also check the AC’s circuit breaker for the same reasons as the GFCI reset button, and reset. 

2. Haier Portable AC Keeps Turning Off

Sometimes your portable air conditioner would turn on but can’t stop going off. The likely reasons for that include the following:

  • Oversized unit – The problem with getting a unit that’s too big for your space is that it will keep going off. So, that should be the first consideration, and below is a table to guide you. If your AC is oversize, replace it with the correct size.

AC Capacity (BTU)Square Footage 
5,500 – 8,500 BTU150 – 250 sq. ft 
6,500 – 10,000 BTU 250 – 350 sq. ft
8,000 – 12,000 BTU 350 – 450 sq. ft
9,000 – 13,000 BTU 450 – 550 sq. ft
9,500 – 13,500 BTU 450 – 550 sq. ft 
  • Clogged filter or coils – If the filter or coils are clogged, the air conditioner will find it challenging to keep the air circulation going. And if it doesn’t breathe properly, it’s likely to go off. So, check the two and clean them. 

  • Tripped breaker – Sometimes the air conditioner keeps shutting off because of a tripped breaker which cuts out its power supply. If that’s the case, reset the breaker and if it continues tripping, replace it. 

  • Refrigerant leak – The refrigerant’s job is to absorb the room’s heat, which enables the air conditioner to run. Once the level drops from leakage, the air conditioner may start going off, and only an expert can check its level and refill it. 

  • Faulty thermostat – A bad thermostat will trick the air conditioner into going off at the wrong time. But to be sure, contact an expert technician on that matter.

  • Dirty air filters or coils – Filthy filters and coils won’t just cause the AC to keep shutting down but are also likely to prevent it from cooling. Thus, clean them—preferably every two weeks, especially the filter. 

  • Unit obstruction – If there is insufficient clearance around the portable unit, perhaps due to obstructive objects or too much dirt, the air conditioner won’t cool. So, ensure you clear any possible blockage around it. 

  • Wrong mode – The only time the air conditioner will cool adequately is when the ‘Cool Mode’ is ON. The AC won’t cool if you pick another mode, such as Heat Mode or Dry Mode. So, ensure you set it on ‘Cool Mode.’

  • Wrong thermostat setting – The air conditioner also cools best below 750F. Once you go higher than that, the unit may start blowing hot air. 

  • Blocked or longer exhaust hose – It’s also essential to ensure the exhaust vent isn’t blocked and that it’s not longer than 5 feet. If it is, then it won’t cool. 

  • Low refrigerant – As indicated earlier, call an expert to inspect and refill the refrigerant. But overall, if a lower refrigerant does not cause the AC to keep shutting off, it’s likely to cause it only to blow air. 

  • Faulty thermostat – A bad thermostat may also be why your air conditioner won’t cool. If so, have an expert check it and fix it. 

4. Haier Portable Air Conditioner Not Heating

Consider these issues if your portable AC won’t blow hot air:

  • Tripped breaker – Once the breaker trips, it interferes with the air conditioner’s power supply, preventing it from heating. So, check it and reset it if it’s OFF. 

  • Wrong mode – The air conditioner won’t blow hot air if it’s on any mode other than Heat Mode or auto. So, check that and ensure you put it preferably on Heat Mode. 

  • Incorrect thermostat setting – You also need to set the thermostat below 750F. Once you go past that, the air conditioner may start blowing hot air instead of cold air. 

  • Dirty filter or coils – The filthiness on the filter or coils interfere with air circulation. So, the AC won’t be able to blow any air, including cold air. 

  • Wrong exhaust connection – The exhaust vent should be appropriately connected to vent the hot air outside. If that’s not it, the AC may not cool as the heat stays indoors. 

5. Haier Portable Air Conditioner Not Draining

The air conditioner won’t drain properly if the drain pipe or the air filter is clogged. So, you must check the two.

First, check the reservoir tank for any debris, which could be why the drain pipe is clogged. And once that’s the case, clean the reservoir tank and the drain pipe. 

Also, check their filter for possible clogging and clean it. It’s overall a good idea to clean the filter every two weeks.

  • Clogged filter – Clogged filters may also interfere with the evaporation of water by your AC. If so, clean them. 

  • Poor drainage – If there is an issue with your AC’s drainage, water won’t evaporate. Thus, check for any drainage slip-ups and fix them. 

  • Faulty condensate pump – Don’t forget to check the condensate pump for fault and replace it if that’s the case. Generally, the water won’t drain or evaporate if the condensate pump is bad. 

7. Haier Portable Air Conditioner Compressor Not Running

Lastly, you can expect your portable AC to have a significant problem if the compressor won’t run. That often happens due to these issues:

  • Clogged filter or coils – If the filter or the evaporator/condenser coils are filthy, the compressor will be forced to work harder to keep the unit cooling. Unfortunately, that may cause it to break down. So, check the filter and coils for dirtiness and clean them if that’s the case. 

  • Lack of power – Simply put, ensure your air conditioner is On. That means reverting to the earlier shared reasons on ‘why your portable AC won’t turn on.’ 

  • Faulty wiring – A wiring fault could short-circuit the compressor and prevent it from running. If so, you need to replace the compressor, and an AC expert can help you. 

  • Faulty thermostat – Sometimes the compressor won’t run, not because it’s defective but because the thermostat is. An expert can help you tell if that’s the case and fix it. 

  • Bad capacitor – The compressor will also fail to run if the capacitor is the problem. An expert can help you inspect the capacitor for fault and replace it

  • Dead compressor – It could also be that the compressor itself is worn-out or damaged, thus unable to run. So, replacing it is an option. 

  • Others – Before replacing the compressor, check if the start relay, selector switch, and thermistor are faulty. If either is defective, the compressor won’t run until you replace it.

Closing Thought:

Above is a Haier portable air conditioner troubleshooting guide to use when your AC won’t work or starts to malfunction. It is handy when you want to avoid a service call.
