Had the same thing happen here. If the thermocouple line shorts out the temperature appears to go runaway (999F or whatever the max of your software is). Ours was a short out in a socket where the thermo plugged in to pass through the frame. Regar

Hello, My first time post up here. I have a problem with thermo runaway on upper zone #5 on the Omni 10 Electrovert. We changed the thermocouple #5 but the problem came back up. We swapped Sensoray board 8 and 9, swapped board #3 (T/C interface boar

What about the relay that controls the heater? I've seen that problem on conceptronics ovens. The relay would latch on and never turn off.

We swapped the solid state relay for zone 5 bottom to zone 5 top but the problem came up once a while. As for noise protection, there are jumpers at E1 to E8 and E9 to E16. They are hardware filters and prevent noise spikes from affecting thermocoupl

The noise kit I'm referring to involves the installation of a new interface card in your PC, a new sensoray interface card in the card cage (brd 7), soldering/bridging of two DC COM points and new DB cables.

Does the t/c read the actual skyrocketing temperature (you could confirm with a profiler if you wanted to leave it running while it's setting itself on fire) or something much lower than reality, driving the heaters harder? I would probably start sw

You might consider installing a noise kit as it sounds like you've tried almost everything else. Electrical interference on these machines causes erratic problems, especially as they get older. I would call Speedline tech. and see if they think the
