Employer Mens Room Hand Dryer Hard-starting
Here is link to unit like ours, for sale: https://m.grainger.com/mobile/produc...ast-Iron-5W630
Issue: Dryer blower in mens room startsup only after multiple presses of button, or, strong slam of button or two. What is causing it to not start after one press every time? There are no discussions of this issue with this blower on line, anywhere. |

Maybe other things. But that's where I'd look first. Or just replace it with a paper towel dispenser..... The towels work without drying your hands on your pants before using that worthless hand dryer..... |

Thanks Jouke, Clifford:
These machines are so ubiquitous you'd think there would be tons of threads about them, and service manuals online. |

Loose wire, or broken button, or damaged motorwinding, or........................ if none of the above then contact the manufacturers' help line! If cheap knock-off, buy a better quality unit.

Looking at that image, it looks like a copy/clone/license of another brand called 'World Dryer'. A youtube video shows a synchronous motor in the guts of the timer.
