    Hi,
    Check blower -M90 if it starts once the lamps are ignited.
    Check the hose connection to dryer slide-in unit +E2 for tears and secure attachment.
    Check differential pressure switch -B110 (behinde electric cabinet lid)
    Take out the slide-in unit, clean it with blast air and put it back.

    Let us know if you still struglle with this problem.

    Good luck.

    Check for loose connections, ensure proper power supply, and inspect the infrared components for any damag
