Profitec Pro 500 PID: Resetting Safety Switches

If your Pro 500 PID has stopped heating, but both green and orange lights + PID remain on, here's a likely fix for that scenario.

Tools Needed:
  • 2.5mm Allen Key

1. Remove the top panel of the machine with a 2.5mm allen key, taking out the 4 screws in the top panel.


2. Press the two buttons on the safety switches to reset them. There's often a very subtle click if they were in the up position.
