My penguin started doing that. I can clean it like it was new and sometimes it just dosent run after it has been off.... I dont know what its problem is.
Do you know anything about electronics. Ex. Do you have a voltage tester.
The motor houseings are just coils of wire that are incased in epoxy. If the coil went out, which happens, then it would stop working.... if you do a continuity check it will show that it is open if there is a short in the coil.
Other than that.... Could it be the outlet that it is in. Have you tried it in other outlets. Or other things in that outlet.
Just what I could come up with.
