I am working this out the Bitmaintech support. They have been pretty helpful. I went to the store and brought an infrared thermometer and opened up a machine at their request. I tried disabling if temperature is above 80 C but it is NOT HASHING at all. I've tested this with 2 different working PSUs and still nothing. I think thermometer and board is defective.
It looks like the thermometer is defective. Here is what I get in my dashboard as well:
