OK - a little more testing. I used the "nightshot" feature of my video camera to look at the IR emitter. It's flashing IR light.

Um...OK. I don't know what that's telling you. On the old style optics when the red LED was blinking the optics is bad and you replaced both emitter and receiver.

Here's the receiver:
W10898445 Cntrl-Elec

Well, for sure it's telling me that the emitter is emitting infrared light. I will note that the led on the receiver isn't lit nor has it ever lit.

Lets see if I can make this easier. Look at this diagram and tell me where you are losing the voltage:

Ok, confirmed, voltage on the receiver board was as expected. 0 volts on emitter board between J1-1 and J1-3. I did get 7 volts across J1-2 and J1-3, for what it's worth. That might have something to do with the infrared emitter actually emitting flashing light. Not sure what that means or how it effects the operation.

What's the voltage on the receiver J1-4 to J1-6. If it's 0V the receiver is the problem.

Sorry - I should have been more clear. 0V across those two pins... Which according to the diagram would correspond to those two pins on the emitter.

I have an identical fridge at work. I'm thinking of swapping out the receiver to test what happens. What do you think?
