Dometic A/C Hard Start Capacitor Description
43-53 UF 250V Cap W/ Hard Start New Style WSX-7
3310727. Starter Motor Kit
The Dometic 3310727. is a motor start kit, also known as a hard start capacitor kit, designed for use with RV rooftop air conditioners—specifically Dometic’s Brisk II and Duo-Therm models
It includes a 43–53 MFD 250V capacitor and a WSX-7 solid-state relay, which work together to give the compressor a boost during startup. This is especially helpful in situations with low voltage, high head pressure, or when using a generator. It can:
-
Reduce strain on the compressor
-
Improve startup efficiency
-
Minimize light flicker and power draw spikes
It’s a direct replacement for older or worn-out starter kits and is compatible with several Dometic and Coleman models.
