Daikin Air Conditioner E7 Error Code
Outdoor fan motor fault. Here is what it means and how to clear it, easiest fix first.
The fan in the outdoor unit isn't running correctly. A failed fan motor, a loose or faulty wiring connection, or something physically blocking the fan blade can all cause it.
Daikin uses this code across its residential split, SkyAir and VRV ranges, but the exact meaning and causes can vary by series, model year and region, so confirm it in your unit's manual. How to read it: most Daikin ductless wall units only blink the operation lamp. On remotes such as the ARC433 series, press and hold the timer Cancel button for roughly 5 seconds until 00 blinks on the screen, then press Cancel again one step at a time; when the indoor unit answers with a long continuous beep, the code showing is the stored fault. SkyAir and VRV wireless remotes use a different sequence with the Inspection/Test, up/down and MODE buttons, and wired wall controllers usually show the code on their screen.
How to fix Daikin E7
Clear around the outdoor unit
With the breaker off, remove leaves, grass clippings, snow or anything stored against the outdoor unit, and keep about 2 ft (60 cm) clear on all sides. Pull away debris resting on the outside of the fan grille and brush loose material off the coil fins with a soft brush; do not use a pressure washer or bend the fins. In winter, clear packed snow and ice from around and on top of the unit.
Look for anything caught in the fan
With the breaker still off, look through the fan grille for sticks or ice touching the blade. Don't put your hand or tools through the grille or remove it; if something is lodged against the blade, leave it for the technician.
Reset the power at the breaker
Switch the system off with the remote, then turn off its circuit breaker in your home's main panel. Wait about 5 minutes, switch the breaker back on and restart the unit. Watch whether the outdoor fan starts when the unit begins cooling or heating.
When to call a technician
If the fan blade is clear and E7 returns, the fan motor or its board connection needs an HVAC technician.

Frequently asked questions
What does E7 mean on a Daikin air conditioner?
The fan in the outdoor unit isn't running correctly. A failed fan motor, a loose or faulty wiring connection, or something physically blocking the fan blade can all cause it.
Can I fix Daikin E7 myself?
Often. The first steps above are safe checks a homeowner can do. If they don't clear E7, the cause is likely a worn part that needs replacing.
What if E7 keeps coming back?
A code that returns after a reset and the checks above usually means a part is wearing out. Note when E7 appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
