What’s up guys? I have a master temp 300 that’s around 10 ½ years old and it giving me some problems. At first it was starting and then would cycle off with an AGS l.e.d light. So I changed the cheap stuff that I haven’t changed in years, high flow, glue and the mister and I’m waiting for the AGS . Still same problem. Then I checked the thermal regulator and found it was not there. No spring, thermostat or clip. So I ordered put it in today. After installing it it started giving me an E01 code. I pulled off the board and found some rust. So after cleaning the board and putting it back, I get nothing now. If I hit the reset button, it will light up at 90 and that’s it. Whatta ya think, change the board?
