What to Do If Your Molder Won’t Turn On or Run
If your molder isn’t turning on, there are several steps you can take to troubleshoot the issue before calling for service. Use this guide to work through possible electrical and mechanical causes.
Step 1: Check the Power Supply
Start with the basics:
- Make sure the molder is plugged in.
- Confirm the outlet has power.
- Reset any external breakers if needed.
Step 2: Check if the Arbor is Moving (Variable Speed Molder only)
Unplug the machine and try turning the arbor by hand:
- If the arbor doesn’t move, there could be a mechanical issue with the bearings in the head or motor.
- If the arbor moves freely, continue to electrical troubleshooting.
Step 3: Electrical Checks
When you press the start button and the molder doesn’t run, inspect the following:
- Thermal Reset on the Baldor Motor: Press the reset button to ensure it hasn’t tripped.
- Breaker in the Control Panel: Check for a tripped breaker and reset it if needed.
- Drive Board Voltage: Use a multimeter to confirm the drive board is receiving proper voltage.
- Fuses (for Older Machines): Inspect the control panel for blown fuses.
Step 4: Inspect the Belt
If the electrical system checks out, examine the drive belt:
- Look for signs of wear, cracks, or looseness.
- Ensure the belt is tensioned correctly and seated properly.
Step 5: Evaluate the Motor
If the machine still won’t run and all prior steps are in order, the motor may be faulty and require service or replacement.
