Their could be 2 rocker switches. One for light and one for fan.
Looked up the model number and their are 2 diff switches. One has 3 wires and the other has 2. The 3 wire switch I believe turns the light on in the freezer and shuts down the fan motor when the door is open. The two wire switch simply turns a light on in the ice box, did you get the 3 wire switch or the 2 wire switch. if you got the 3 wire switch it will work but ya gotta connect the correct 2 terminals up. Thats just whats on my mind.
