How To Fix A Mini Split E7 Error Code

It’s crucial to remember that this guide is just meant to be used for informative purposes before we begin. If you’re not comfortable working with electrical equipment, it’s best to contact our professional HVAC technician for assistance.

Step 1: Turn off the Power to your System

The first step in resolving an E7 error code is to turn off the power to your system. While you concentrate on resolving the problem, this will help avoid any more harm to your equipment.

Step 2: Check the Wiring

Next, you’ll want to check the wiring connections between your indoor and outdoor units. Verify that no wires are loose and that all connections are tight. In the event that any connections are found to be loose, tighten them and check to see whether the problem code has been fixed.

Step 3: Check the Circuit Breaker

If the wiring connections look good, the next step is to check the circuit breaker that powers your system. Ensure the breaker hasn’t tripped, and the switch is in the “on” position. Reset the breaker if it has tripped, then check whether the problem code disappears.

Step 4: Clean the Air Filters

Dirty air filters can also cause communication errors between your mini split system’s indoor and outdoor units. Take a few minutes to check and clean the air filters in both units. If the filters need to be cleaned or replaced, do so and check to see whether the problem code disappears.

Step 5: Reset your System

Try resetting your system to see if it works to fix the E7 problem code. You may accomplish this by briefly shutting off the power to your system, then turning it back on. This will often clear communication errors between the units and resolve the error code.
