Appliance Operation (cont.)
Sequence of Operation
USER ACTION!
For more information regarding a appliance's temperature control adjustment or general sequence of operation,
please see our Temperature Control Adjustment—Sequence of Operation Manual in our resource library at
truemfg.com/service-manuals/sequence-of-operation or scan the QR code.
When the appliance is plugged in…
1. Interior lights will illuminate on glass door models (see previous page for light switch location).
2. An electronic control with digital display will illuminate.
3. The display will alternate between hSt and dLY, indicating a delay. This delay allows the appliance to reach temperature without a
false alarm. For more information, see “Health Safety Timer: Operation” on pg. 25.
Total Freezer Delay: 105 minutes
Total Refrigerator Delay: 60 minutes
4. There may be a short delay before the compressor and/or evaporator fan(s) start. This delay may be determined by time or by
temperature, which could be the result of an initial defrost event that will last at least 6 minutes.
a. At the start of every compressor cycle, the condenser fan(s) will reverse for blow dirt off the condenser coil.
5. The temperature control cycles the compressor and evaporator fan(s) on and off together as determined by the set-point and
differential temperatures.
a. The set point is the adjustable pre-programmed temperature designed to match the average appliance temperature.
b. The differential temperatures are the non-adjustable pre-programmed temperatures used to determine when the compressor
shuts off and turns on.
6. The temperature control/thermostat senses either an evaporator coil temperature or air temperature, NOT product temperature.
7. An analog thermometer, digital thermometer, or electronic control display may reflect the refrigeration cycle swings of up and
down temperatures, NOT product temperature. The most accurate method to determine an appliance's operation is to
verify the product temperature.
8. Every appliance requires a defrost event to ensure the evaporator coil remains clear of frost and ice buildup. The electronic control
is preprogrammed to initiate defrost by interval.
9. An electronic control with a digital display will show dEF during defrost.
NOTICE
The electronic control with a digital display will alternate between hST and dLY for at least 30 minutes after
defrost has terminated.
a. A refrigerator will use the evaporator fans to clear the coil during defrost.
b. A freezer will use heaters to clear the evaporator coil during defrost.
NOTICE
The evaporator coil heater and drain tube heater are only energized during defrost. Defrost is terminated
when a specific evaporator coil temperature is reached or by a time duration.
