Abnormally High Discharge Temperature / Insufficient Refrigerant / THOD Defective

What does E36 mean?

The compressor discharge temperature is abnormally high. This can be caused by insufficient refrigerant, a defective compressor discharge temperature sensor (THOD), or other system issues leading to compressor overheating and potential damage.

• Compressor discharge temperature sensor (ThOD, e.g., P18) is defective.
• System is critically low on refrigerant.
• Excessive heat load on the compressor.
• Faulty compressor cooling mechanism.
• High discharge pressure reducing cooling efficiency.

Click steps to track your progress.

1. 1

   Verify the refrigerant charge in the system using a manifold gauge set.

2. 2

   Measure the resistance of the compressor discharge temperature sensor (THOD) and compare to specification.

3. 3

   Inspect the condenser coil for obstructions or dirt, ensuring adequate airflow across the coil.

4. 4

   Check for proper operation of the outdoor fan motor and fan blade integrity.
