There’s nothing more frustrating than expecting your trusty mini split system to keep you cozy in winter, only to find the mini split not working in heat mode. But don’t worry, it’s possible to tackle this issue step-by-step and get your mini split warming up the place once again. Let’s roll up our sleeves and get started!
Mini Split Not Working in Heat Mode? Check the Basics
Before diving into complex troubleshooting, let’s ensure we’ve covered the basics. Verify that the mini-split is receiving power by checking the circuit breaker and ensuring the unit is turned on. Sometimes, the simplest things can be the culprit!
Clean the Filters
Clogged air filters are a common reason for heating problems. Dirty filters obstruct the airflow, making it difficult for your mini-split to generate warm air efficiently. Remove the filters and give them a good cleaning. If they are damaged, consider replacing them.
Inspect the Thermostat Settings
When your mini-split seems to be acting up, it’s tempting to dive into complex troubleshooting. But before you do, take a moment to check the thermostat settings — it’s a simple fix that often does the trick! Make sure the thermostat is set to your desired temperature and the mode is on “Heat.” Accidental adjustments or mode oversights can happen, causing unexpected heating issues. If you have a smart thermostat, ensure it’s connected to your Wi-Fi and synced with your preferences for hassle-free control.
Check the Remote Control
If your mini-split system uses a remote control, replace the batteries and ensure there’s nothing blocking the signal between the remote and the unit. A weak or obstructed signal might result in issues with mode changes.
Verify the Mode Timer
Some mini-split systems, have built-in timers that allow you to set specific operation periods. If you experience your mini split or Mitsubishi mini split heat not working, check the timer settings. Disable them if you don’t intend to use them. Incorrect timer configurations can cause the heat mode to turn off unexpectedly.
Examine the Outdoor Unit
The outdoor unit of your mini-split is vital for efficient heating. To ensure its optimal performance, let’s make sure it’s free from obstructions that can hinder its airflow. Uninterrupted airflow is crucial for your mini-split’s efficiency during heating mode. The outdoor unit houses essential components responsible for generating heat, and proper airflow allows them to work at their best.

However, this opens up the possibility of an additional problem with ductless mini splits: getting stuck in one mode. If your ductless heating system seems stuck in air conditioning mode this winter.
