AIRXCEL 9430-351 Thermostat



The thermostat wiring is factory installed by the OEM (Original Equipment Manufacturer). RV Products suggests the thermostat wiring be a minimum of 18 gauge. The thermostat is intended for use with a 12 VDC control circuit that does not exceed 1 amp. The thermostat is equipped with a replaceable 2 amp fuse located on the base of the thermostat. The fuse is designed to “open” if the circuit is mis-wired or if there is a short in the system. Before replacing the fuse, the cause of the failure must be located and corrected.

Caution This thermostat should be installed by trained technicians only. Adhere to all local and national codes and ordinances. Disconnect all power to the system before installing, removing, or cleaning.


The display indicates the mode and the room temperature. When the mode button is pressed once, the thermostat will wake. If your thermostat is equipped with a backlight, the backlight will illuminate. When the mode button AIRXCEL-9430-351-Thermostat-6 is pressed again, the mode will change. Press theAIRXCEL-9430-351-Thermostat-7button to wake the thermostat; the set temperature will display and the mode will flash. Press theAIRXCEL-9430-351-Thermostat-7button again to change the set temperature. The thermostat will return to sleep mode after 5 seconds if no button is pressed.
There is a three minute anti-short cycle for cooling. After the cooling system has been de-energized, the system will not energize again for three minutes, to protect your compressor. To bypass the anti-short cycle, change the mode to OFF.
Note: Operating your cooling system when the outdoor temperature is below 50°F can cause damage to your cooling equipment.
