I have an AIM 84BD with a Fuji PXV-3 ramp/soak control. I've had it for about 3.5 years. It has suddenly turned on me! First it began (about 2 firings ago) to briefly buzz (like a door buzzer) for about 4-6 seconds when it kicked into heat cycle to maintain 1500F. Since it did it's think ok, I used it again, with the same buzzing, which seemed to diminish/stop as it fired (for about 2 hours). Now I wonder if it wasn't suiciding (with my ignorant assistance) -- today I turned it on, and it buzzes at a lower volume continuously, gets to around 600F, then s l o w l y the display rises at 1 degree every 3-4 seconds. At that rate, my glass will be ready next week.... The coils, while clearly heating, never get 'orange' as they're supposed to, or perhaps I don't have the patience to wait until they do...I just swear and switch the thing off.
Any suggestions for treating the patient? I can't afford a replacement right now.
