What to do if the fuse keeps blowing on my Mold-Masters E-Multi EM1?

  Troy HartAug 17, 2025
  If the fuse for a zone has failed in your Mold-Masters Controller, it indicates a fault external to the controller. You should identify and fix the fault before replacing the fuse. Replace it with a fuse of the same rating and type, such as a High Rupture Current load fuse. The blown fuse can be found either on the control card or on the off-board triac module, if one is installed.

  If your Mold-Masters Controller detects an open circuit thermocouple, for immediate recovery, you can slave that control zone to an adjacent zone or switch to open loop control. Afterwards, check if the input fuse on the control card has ruptured. If the fuse is intact, then replace the thermocouple.

How to troubleshoot a thermocouple reading -100C on my Mold-Masters Controller?
- L
  Lisa LyonsAug 23, 2025
  If a thermocouple on your Mold-Masters Controller displays -100°C, indicating it's defective, test the thermocouple at the support beam or hot runner connector. Thermocouples in the same area should show similar output. If the output differs significantly, replace the thermocouple. If the new thermocouple also reads -100°C, there's likely a wiring problem; inspect the wiring and connections.
