    I know some of you have this unit....

    Just started getting a heavy buildup of frost on the evaporator of my unit. The manual says it could be the Defrost Thermostat or the System Controller Relay Unit. Anyone have this issue or any experience maintaining this thing? i am pretty handy, just will have no idea what is what when i open it up. Maybe I will take a picture when I open it and see what i can figure out.

    I did not call the number in the manual yet as i know they no longer make this unit. I will give it a try at some point...

    Sent a note to the folks at North Road, who purchased Nyle. They got back to me within hours and let me know that the issue is most likely not as it says in the manual. He says it is most likely the Speed Control that is stuck in low. The speed control normally slows the fan down when it is warmer.

    He is going to send the part. Hopefully it gets here quickly and I can get this thing back running. I like the fact that it heats water but I like it better that it maintains the cellar temps in the garage/basement where I have the beer cellar - and some wine too.

    Ja, I was going to suggest maybe not enough air flow. I've seen air conditioners ice up when too many of the vents are closed, choking down the total air flow.
