We usually travel to the continent each summer. On several occasions we have found that the fridge does not cool as well as we would like.
I have just fitted a cooling booster fan to force air over the cooling tubes at the back of the fridge.
The following photos show the installation on a Dometic RM8505 fridge/freezer,
1. 12volt DC picked up from the back of the fridge. This view is with the bottom external grill removed.
All of the following views are with the top external grill removed.
2. 12volt connections showing the 12volt DC 'mains', switch wire from the On/Off switch and the fan connections.
3. Temperature sensing device attached above the radiator fins at the back of the fridge.
4 Fan clipped to the rear of the top grill using cable ties
5. On/Off switch illuminated
6. External view of the top grill with fan fitted behind. Using clear cable ties, the ties are virtually invisible.
Overall the installation took less than a half day to complete. The fan and switch cost about £10. The most difficult part was finding a cable route to the On/Off switch.
Note that the fan is intended for a computer and is supplied with a 3 core cable and a plug. Cut off the plug. It is essential to connect it correctly. The black core is GND, the yellow core is +12Volts DC (from the On/Off switch). The green(blue?) cable is not used and is cut off. Incorrect connection will damage the fan ( I have the teashirt).
When the switch is turned on at say 25C the fan runs at 300rpm provided the temperature sensed behind the fridge is under 30C. If the temperature is above 30C behind the fridge the fan speed is dependant on temperature up to 38C when the fan runs at full speed of 1350rpm.
I don't yet have any experience of the performance of the fan, however it has been recommended on other forums as being very effective in higher ambient conditions.
