Call for service.

These things are complicated & dangerous.

Turn it off, and call a service company to come out and fix it.

Then set up an appoimtment to have it cleaned.

Sonds like the main controller is at fault.

There many controls on a unit.
But the main controller signals the other controls to operate.

Call your local company to check the unit.
