I have a tempstar PA5542AKA6 package unit with electric heat AMMK15AHB2 Serial#G043050734 that I had a circuit board replaced in a two years ago. The tech said he had to put in a replacement because the original was no longer available. Can anyone tell me what the original board was? He replaced it with HQ110752UT I can not find the info on either.
