Before replacing Controller that does not show a visible defect and that you suspect is bad,
conduct the following check procedure. This procedure will help you verify your
diagnosis. Always choose a neutral to establish a good neutral connection when
checking high voltages. Also, confirm there is a good power supply and neutral connection to
controller: 115VAC at terminals #6 (Brown) to neutral #7 (White).
Alarm Reset: To silence an alarm, press and release the upper or lower button with power
on. For alarm information, see "III.D.Alarm Safeties".
Startup/Cool Down
1) Check that all wiring connections are properly connected.

3) Check for 115VAC at terminals #6 (Brown) to neutral #7 (White). If 115VAC is not present,
check power supply, wiring connections, and power switch continuity.

115VAC is not present, replace controller.
Defrost
6) Manual Defrost Check: Press and hold the snowflake button until "Snow flake icon"
appears on display.
7) Confirm Comp, CondFM de-energize. The EvapFM must be energized during defrost time.
8) Check that the components restart after defrost termination.
After 25-min of defrost time, the snowflake icon in the display must turn off, and the Comp
icon must be blinking in the display, 3-min. Comp delay timer starts, after the delay timers
terminate the Comp and CondFM energize.

D. Thermistor Check
The cabinet thermistor (NTC type) is used for cabinet temperature control; the thermistor
resistance varies depending on temperature. The controller monitors the thermistors to
