Dometic Duo-Therm Solenoid Coil Harness | 3310714.005 | OEM

Restore reliable solenoid operation on your Dometic RV air conditioner with the Dometic Duo-Therm 3310714.005 OEM Solenoid Coil Harness.

What This Does

The solenoid coil is a critical control component in the AC refrigeration system. When the coil fails, symptoms typically include improper valve operation, refrigerant flow issues, or heat pump mode failures on units equipped with reversible cycles.

Direct Replacement for Later-Version Coil 3109864.003

Direct drop-in replacement for the later-version coil part number 3109864.003. If your existing coil carries this part number, the 3310714.005 is the current OEM replacement.

⚠️ Replacing an Earlier-Version Coil? Modification Required

Important installation note: if you're replacing the earlier version coil (3105504.009) AND wire harness (3105505.014), the small screw hole will need to be enlarged so that the stud on the valve assembly will fit. Plan for this modification during installation.
