On the downside, they’re proven to throw out error codes. With some knowledge up your sleeves, you’ll be able to better maintain your system for years to come. Hence, today we wanted to go over some of the most common mini split error codes, what they can mean, and how to avoid and or address them.
Mini Split Troubleshooting: Common Error Codes & Solutions for NY & NJ
DF on Mini Split
This is a sign that your outdoor unit has frozen and now the system has entered into defrost mode. If you live in an unusually cold climate, this can be a rather common occurrence.
To assist, you can try turning the temperature down on your end to ease the pressure on your outdoor unit. Ultimately, if experiencing extreme conditions, the mini split DF code is the system protecting itself from further damage, and you’ll simply have to wait out the defrost cycle.
E1, or a Communication Error
The E1 code on the mini split typically occurs when the indoor and outdoor units struggle to communicate. This can be brought on by poor wiring, electrical issues, or problems with the control board.
To resolve, make sure all electrical connections are secure. Prep for power surges and install a surge protector. And as always, schedule routine maintenance to keep an eye on the system components.
E2, or an Indoor Coil Temperature Sensor Malfunction
This sensor is meant to detect refrigerant levels and based on those readings cools accordingly. If an error appears, your system is more than likely no longer properly cooling.
Sometimes, you just have to have a pro come out and replace bad sensors. However, upkeep does play its part. By keeping coils clean and filters changed you can prevent sensor obstructions and prolong their function.
E3, or an Outdoor Fan Speed Error
This is an indication that your outdoor fan is having some trouble. It’s either running too slowly or not at all. This can result in a system malfunction due to overheating if not addressed.
To fix, first be sure that all wiring is secure and in place. Then take a look at the motor to make sure it’s doing its job and maybe even add some lubricant if needed. Simplest of all, is to make sure that your outdoor unit is clean and clear of things like leaves, snow, and everything in between.
E4, or a High Discharge Temperature
A clear sign that the system, or better said the compressor, is overheating. This can happen due to a slew of reasons (like dirty coils, low refrigerant levels, or blocked airflow). So a bit of investigating may be needed.
As always, keep your system and your filters clean, check for blockages, and if in doubt call a professional to take a look.
P1, or Unsafe Voltage Levels
The P1 code on a mini split is an important one. Whether high or low, it doesn’t matter, the system has deemed the voltage reading unsafe. If left unattended, it can lead to damaged components.
This again comes back to the home’s electricity. So making sure the electrical system is properly grounded and using things like surge protectors are a good idea. Also, we would advise against using high powered appliances and your mini split in the same circuit.
P4, or a Compressor Drive Error
This typically points to a malfunction in the compressor drive which could then lead to system failure. Honestly, just like the human body, the parts of your mini split are all connected. If unaddressed, related issues with overheating or electrical malfunctions can occur.
To keep things running smoothly, be sure there’s adequate airflow around the compressor. And you should know the rest — keep it clean, and call a pro when needed.
