Possible Causes
Worn contacts in infinite switch, Shorted regulator, Miswired replacement switch, Knob not engaging shaft properly
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before removing control knobs or panels.
- Knob check: Ensure the knob is not cracked and is firmly attached to the switch shaft.
- Test switch: Remove the back panel of the control area and test the infinite switch terminals according to the wiring diagram. If it does not open/close correctly at different settings, it is faulty.
- Inspect wiring: Confirm wires are on the correct terminals; miswiring can cause full-power operation only.
- Replace switch: Install a new Etna-compatible infinite switch/energy regulator for that zone.
