    MES 40 Digital Rebuild

    Thanks for all the replies here everyone. I got my project finished up today. I ended up opening the back to run all new wiring, as well as cut an access in the back for the snap disc. My hole ended up a little wide so I'll seal around the j-box with some foil tape or whatever else I can think...

    MES 40 Digital Rebuild

    Yeah, I did the rewire at the circuit board panel this afternoon and ordered a new element & the PID. Then I got to thinking maybe the rollout cutoff might be part of what's been giving me trouble. I'll hook the PID in and if I can't keep the temp I want due to the cutoff, will bypass the...

    MES 40 Digital Rebuild

    In wiring this way and adding a PID, am I completely bypassing the hi-temp snap disc you mentioned earlier? And the other wires from the control board harness that are connected to the circuit board just remain in place but won't be doing anything now?

    MES 40 Digital Rebuild

    Ok I'm checking out my unit to better understand the rewiring. I'm not 100% sure which gen this unit is, I have the control panel top center rear, vent top rear right. My circuit board is different than your example. In fact I didn't even have to drill out any rivets, the cover plate was...

    MES 40 Digital Rebuild

    Ok you've just about got me convinced to go this route. Is it a good idea to replace the heating element at the same time?

    MES 40 Digital Rebuild

    So in changing to the PID, does the the MES power cord get plugged in to the PID, or still into the building power supply? Seems like a straightforward project, just trying to wrap my head around the whole thing.

    MES 40 Digital Rebuild

    Yeah, I've read his thread about changing to a PID unit, I was hoping to avoid that route at least for now. The longer I've had this MES40, the more I wish I never got rid of the UDS I built and ran for years. That was the best smoker I ever had.

    MES 40 Digital Rebuild

    I have a Masterbuilt MES 40 with the typical temperature control problems, MB21072719. I'd like to try repairing rather than buying a whole new smoker right now. Planning on replacing the control panel, heating element and maybe circuit board if necessary, but what about the temperature sensor...
