Coleman Mach Freeze Switch 7330A3231 for RV AC
Coleman Mach Freeze Switch 7330A3231 for RV AC — Product description
When your Coleman Mach RV air conditioner starts freezing up or won't cycle right, the freeze switch is often the culprit. This is the genuine Coleman Mach replacement, part 7330A3231. It senses evaporator coil temperature and cuts the compressor before ice builds up, so your AC keeps blowing cold air on a hot afternoon.
The freeze switch is one of those small parts that does a big job. Tucked into your Coleman Mach air conditioner, it watches the temperature of the evaporator coil. When the coil gets too cold, it opens the circuit and shuts the compressor off for a bit. That's what keeps a sheet of ice from forming across the coil and choking off your airflow.
If your rooftop AC has been running but not cooling, cycling oddly, or you've spotted frost on the coil, a failed freeze switch is a common cause. It's an inexpensive fix that can bring a tired unit back to life.
This is part 7330A3231, the genuine Coleman Mach freeze switch. It fits a wide range of Mach models, including the 6797, 6799, 7330, 8330, 8530, 9330, and 9530. Before you order, match the part number on your old switch to be sure. If you're comfortable pulling the shroud and working around the control box, it's a straightforward swap. If you're not, any RV tech can handle it in a few minutes.

Frequently asked questions
What does the freeze switch do?
It monitors the temperature of your AC's evaporator coil and shuts the compressor off when the coil gets too cold. That stops ice from building up on the coil and blocking your airflow.

It fits the Coleman Mach 6797, 6799, 7330, 8330, 8530, 9330, and 9530 series air conditioners. Always match the number on your old switch before ordering to be sure.
How do I know if my freeze switch is bad?
