Fridge Condenser Fan Temp Sensor Location
I installed a new cooling unit last fall, and it really seems to perform well. When I bought it from RV Cooling Unit Warehouse it was recommended that I install a pair of fans aimed at the condenser fins on the cooling unit to aid in hot temperature cooling.
The fans came with a digital controller which has a temp. sensor. The sensor can be used to monitor either the ambient temp behind the fridge or it can be mounted on the cooling unit itself. The sensor is to turn on the fans only when needed so they don't needlessly consume power.
These fans are being mounted directly under the condensing fins and are intended to direct airflow across the fins to aid in removing the heat from them.
Questions I have are:
1) Is it better to use ambient temps or the cooling unit temps to determine when the fans come on? My hunch is that it's better to measure the temp of the cooling unit tubes, so that the fans only come on when the unit is actively cooling.
2) Where to mount the temp sensor? If measuring ambient temps, I assume somewhere about 3/4 of the way up the cavity behind the fridge. But I'm leaning towards mounting it on the cooling unit and can't figure out where to mount it.
The minimal instructions talk about mounting it on the absorption coil tubing just above the boiler, and seems to indicate that that area will be about 95 degrees when the unit is running. Does this sound correct?
Are there other options for where to mount the sensor that might be better?
3) What temp settings should be used to control the on/off for the fans?
