Evaporator freezing

Hello
I was following up on your question looking for any service bulletins that could this issue and they do not have any currently. I would also look for door sealing issues or doors not closing properly. Sometimes shelves or food will block the doors from closing all of the way, in return frost build up on the coils. Also kids leaving doors ajar overnight. Check door seals thoroughly to make sure there are no rips. One more thing to check is the boards you installed. Call your parts distributor with the model and serial number to verify you installed the correct boards. We have seen boards that look exact but be different by the serial number. Just last week we had one that looked identical we ordered by model number only and harnesses were exact, the unit ran fine but randomly dispensed ice. after research we found it was the incorrect board.
