ARP Fridge Defend - Boiler temp shows 329F - new install

Your temp is normal. The Norcold recall temp switch kicks out when boiler goes over 700 degrees. The ARP is designed to kick out earlier. The purpose of the ARP is to monitor the Boiler temps and when ventilation is bad or the unit is off level,(things that cause the boiler temp to rise and destroy a CU), it shuts the refer off until the boiler temp drops to a safer level. It protects the RV'er from unsafe/bad operation that degrades or ruins a CU. Doug
