I don’t know what’s going on.

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?

That board is toast. With no thermal regulator your internal bypass valve may be bad as well.
