E36 - Abnormally high discharge temperature, insufficient refrigerant, or THOD sensor defective

What does E36 mean?

This code indicates that the discharge temperature is abnormally high, there's insufficient refrigerant in the system, or the compressor discharge temperature sensor (THOD) is defective.

• Insufficient refrigerant (low charge or leak).
• Faulty compressor discharge temperature sensor (THOD).
• Overheating compressor due to system issues.
• Restricted refrigerant flow.

Click steps to track your progress.

1. 1

   Turn off the main power to the AC system at the circuit breaker and allow the unit to cool down.

2. 2

   Check for any visible ice formation on the refrigerant lines, which might indicate low refrigerant.

3. 3

   Contact a qualified HVAC technician to check refrigerant levels, inspect the THOD sensor, and diagnose any overheating issues.

4. 4

   Do not continue to operate the unit as high discharge temperatures can damage the compressor.
