Refrigerator heat sensor tripping
Have a Norcold model 1210 refrigerator with a heat sensor. When we get a driving rain the sensor trips and gives error code F1 oP. At this point we shut the unit off and when the driving rain stops ch...

Isn't the "sensor" itself of the iron-constantan thermocouple design? If water gets to this "sensor" the "box" would just see a lower temperature. My guess is that water might be begetting to the "box".
Perhaps, the "box" is designed to shut down the system if it reads a certain low temperature, as well as a high temperature.
No, the sensor only trips if it sees 700 degree or higher. The normal operating temp is 350 degrees. No low temp trip at all. Water will indeed trip a recall box. This happens when people wash the RV and get hi pressure spray thru the lower access door and saturate the recall box. It is an electrical PC board and will react to water and malfunction like any other electrical board. Doug
I'm just not familiar with all the different installation configurations. I've only worked on conventional Class A installations where there's a standard louvered exterior wall access cover, and a roof vent. It was hard for me to see how enough rain water could reach the circuit board inside the "black box interrogator".
Except for the exception with bug screens I posted, I also fail to see how enough rainwater could access that recall box since it IS mounted a foot above on the back cooling unit tubes. I have NEVER had or seen a 1200 have a rain water leak trip until this posting. The ONLY time I have had the water problem was when the customer washed the RV and the water was sprayed into the lower door and too much water was used. Doug
