VENTILATION
Fan
Fan operation is controlled by a temperature sensor in the
DC power supply circuitry. The sensor turns on the fan whe
the temperature reaches 95
°F (35 oc). Fan location for the
DE00411EV0041 is shown in Figure 3. Fan location for the
DE00611EV0061 is shown in Figure 4;
Amp Draw
The DE I EV 0041 fan motor draws 0.15 amps@ 24 volts.
The ED I EV 0061 fan motor draws 0.10 amps @ 24 volts.
Service and Maintenance
Chirping or rattling noise usually indicate worn fan motor
bearings and required fan replacement. Fan blades should
cleaned annually. Dust buildup on fan blades can be
cleaned using a small brush to dust off the top and
underside
of each blade.
Overheating Protection
DE0041 T and DE0061 Tare equipped with overheating
protection sensa. The sensor is
in the DC power supply
circuitry.
It shuts off power to the compressor and sounds
an intermittent beeping alarm if the temperature in the DC
power supply reaches or exceeds 11 oo F ( 43° C).

Overheating usually results from operating the refrigerator in
high ambient temperatures of 11 oo F ( 43° C) or higher.

blades.
To restart the refrigerator after correcting the cause
of overheating:
Refrigerator operation cannot be restored until the air
temperature
in the enclosure falls below 11 oo F ( 43o C).
1. Tum off the refrigerator.
2. Allow the air temperature in the enclosure to cool below 95"
F (35° C).
3. Tum on the refrigerator.
