Carrier EH60 error code

What it means

EH60 means the indoor unit is not getting a valid room-temperature reading. The unit may not know the actual room temperature.

Urgency

Likely causes

1. Carrier Table 4 identifies EH60 as indoor room temperature sensor (T1) error.
2. A sensor reading/circuit that remains invalid after the manual's wait/reset guidance.

Homeowner fix

Turn the system off with the remote, wait about 10 minutes, then power cycle once at the breaker or disconnect if you can do that safely. If the code returns, stop resetting and schedule service. Do not open the indoor or outdoor cabinet.

When to call a pro

Call a licensed HVAC technician if EH60 returns. Tell them Carrier identifies EH60 as indoor room temperature sensor T1 error.

Repair vs replace

This is normally a repair diagnosis, not an automatic replacement signal. If a technician confirms a major board, compressor, fan-motor, or sealed-system repair on older out-of-warranty equipment, compare the quote with replacement.
