When replacing a faulty thermistor, it is necessary to: 
a) Verify the control module calibration. 
b) Replace both the cabinet and defrost thermistors. 

1) Unplug the unit from the electrical outlet.
) Remove the panels and the top cover over the evaporator.
3) Open the control box cover.
4) Disconnect all thermistor leads from the control module.

Note: The control module has been factory adjusted to the original thermistors. 

Therefore, calibration must be checked and adjusted when replacing thermistors 
only.

5) Connect the new defrost thermistor leads to the terminals of SEN. The red lead 

connects to terminal "S" and the black lead connects to terminal "G".  Be sure wires are 
not touching at the terminal block.

6) Connect the 3°F resistor (included in HS-3540 kit) to SEN1 terminals "G" and "S".
7) Securely close the control box cover.
8) Plug the unit back in.
9) Press and hold the up arrow button on the control module while turning the power 

switch to the "ON" position. Temperature is displayed.  

10) If the display reads 3°F, the control module is properly calibrated. Skip to step 0. If the 

display does not read 3°F, the control module must be reset and calibrated. Continue 
to step 11.

2. Reset Control Module
11) Enter the menu for the control module by pressing the down arrow button and the "°F" 

button at the same time and release. The display should now read "dIF." Press the "°F" 
button until it reads "CAL" - press "°F" once more it should read "00."

1) If it 

does read "00" skip to step 15. If it does not read "00" press the up or down arrow 

button to change it to "00." 

13) Press the "SET" button and wait for the temperature display to stabilize.
14) If the control reads 3°F, the control is properly calibrated. Skip to step 0. If the control 

does not read 3°F, the control module must be calibrated. Continue to step 15.
