I have a machine that either hangs up around 67-70 degrees and never gets up to temp or it will go all the way up to 90 degrees and finish the heat cycle. Most of the time it does not get up to full temp. I have changed NTC2 & NTC3, swapped known good actuator test board, sensor board, function board, Power logic board. Replaced heater rod and TRIAC. I also verified the temp with a 90XL is very close in heat mode. I looked at cables but I didn't see anything obvious. When NTC2 is pulled from distribution it will put the 113V at the heater rod. Anyone ever seen this before?

UPDATE: the EEPROM was the cause. Didn't catch it at first because I swapped it out with another function board.

Hi, just had this similar issue. Temp around 92 in heat dis. But around 6 min. Remaining, temp starts lowering and just before it finishes it drops below 80. It was the triac, it actually broke away from the base of the power supply.
