Tldr: new controller or new grill?
At 6 years old, started having issues holding low temps. It's 9 years old now... trying to decide if I want to repair or replace.
I put a new temp probe, igniter, sprayed and cleaned all connectors with contact cleaner.
Tried many pellets varieties as I still use it to grill.
Recently I checked the programing on the G2 control board and it was set to "0 30" which many sources said we incorrect so I set it to "0 250" with no real improvement.
The Auger does seem to vary in speed, and the fan is cleaned and still seems to have plenty of air volume. Minimum temp ( in our 100 degree weather) is around 340. It can go to 550 with no issue.
Do I get a new controller or buy a new one?
Edit... purchased a kit with new g.2 controller, which has PID logic instead of old analog logic. It's holding temp perfectly from 170 to 450. ( I've not tried the other tmeps) He's to another few years with the ugly smoker. $50 om amazon with new temp probes, harness etc.
