What it means

H7 means the fan inverter/power module temperature is abnormal on applicable outdoor units. Homeowner checks stop at outdoor airflow.

Urgency

advisory

This is not usually an immediate safety hazard, but do not keep resetting it. Try the safe homeowner check below; if the code comes back, schedule service.

Likely causes

  1. Debris, ice, or a foreign object restricting the fan
  2. Loose fan-motor plug, damaged fan lead, or bad feedback signal
  3. Fan motor winding, phase, or rotation fault
  4. Control board fan-drive fault after the motor checks out

Homeowner fix

Turn the unit off, clear only loose debris around the outdoor unit, and restore power once after it cools. If H7 returns, stop using the unit.

When to call a pro

Call a licensed HVAC technician if H7 returns. Tell them the MXM table lists fan IPM temperature error.

This code points to electrical or inverter work - get repair quotes from contractors in your area.

Repair vs replace

This is normally repairable, but it is not a homeowner repair. If the unit is older, out of warranty, or a technician quotes a major compressor, inverter, board, or sealed-system repair, compare the quote with replacement.

For your technician

Technician note: check outdoor airflow, fan drive/IPM cooling, heat sink contact, fan motor load, and outdoor PCB. Page context: Daikin maps this display to the AURORA R-32 line; source: Daikin Nineteen, ATMOSPHERA, Entra, and MXM/MXT/MXTH local service manuals; display convention: match the letter H and seven marker exactly before comparing neighboring codes.

Which systems show it

  • Daikin current US residential R-32 ductless single-zone systems, including AURORA R-32, ATMOSPHERA R-32, Entra R32, OTERRA R-32, and Nineteen-series style high-wall diagnostics where the same Daikin A/C/E/F/H/J/L/P/U code family is used.
  • Daikin concealed-duct/FDMQ indoor units where the Nineteen service manual explicitly lists the same indoor drain, fan PCB, remote-controller, and FDMQ-only C/U codes.
  • Daikin AURORA Multi R-32 and Standard Multi R-32 MXT/MXTH/MXM systems where the MXM engineering manual lists the same homeowner code table.
  • MXM/MXT/MXTH multi-zone systems for the additional multi-zone U-series and inverter/control codes specifically called out from the MXM manual.
