How to Fix / Troubleshooting

Safety: Only work on electrical components if you are competent. Turn off power at the main breaker before opening the electrical compartment.

  • Check supply: Verify the dedicated breaker for the Kospel furnace is on and not tripped. Reset if necessary.
  • Inspect power cable: Ensure the power cable to the furnace is intact and firmly connected.
  • Check internal fuse: With power off, open the electrical panel and locate the main fuse on the control board. Replace with the same type and rating if blown.

If the fuse blows again immediately, there is a short circuit that must be diagnosed by a technician.
