Midea EH62 error code

What it means

EH62 means an evaporator coil inlet temperature sensor circuit is open or shorted on applicable indoor units. The system cannot safely use that coil-temperature reading.

Urgency

Likely causes

1. Brief power event, brownout, or unstable supply voltage
2. Loose power connection, reactor, or outdoor electrical component problem
3. Inverter/IPM protection or current-detection fault
4. Compressor winding, drive, or outdoor board fault after power checks pass

Homeowner fix

Turn the system off with the remote, then power cycle once at the breaker or disconnect if you can do that safely. Expected result: a temporary control fault clears; if the code returns, stop resetting and schedule service.

When to call a pro

Call a licensed HVAC technician if EH62 returns after one reset. Tell them the code points to the AHU/indoor evaporator T2B sensor circuit.

Repair vs replace

Sensor and communication faults are usually repairable. Compare repair with replacement only if the system is older, out of warranty, or multiple boards/sensors are being quoted together.

For your technician

Technician note: section 7.2 lists EH62 for AHU-type T2B open/short; use section 7.4.1.5 sensor checks. Page context: Midea maps this display to the Advantage Series Multi-Zone line; source: Midea D5CMRA Installation Instructions Table 20 and shared ACiQ/Midea Multi-Zone Service Manual; display convention: match the letter E, letter H, and sixty two marker exactly before comparing neighboring codes.

Which systems show it

• Midea Advantage Series Multi-Zone D5CMRA R-454B outdoor condensers and matched indoor units covered by Table 20.
• Midea Advantage Series Multi-Zone High-Heat D5CMHA systems where the D5C installation/error-code convention is shared.
• Midea current R-454B single-zone high-wall families when the indoor display uses the same EC/EH/EL/PC homeowner code convention.

Sold under more than one brand

Also sold as ACiQ. Midea and ACiQ document this code from the same manufacturer source, so EH62 means the same thing on either badge and the steps above apply.
