Honeywell Air Purifier model 18155 simply won't...

Question

Hi! I recently borrowed my mother's Honeywell Air Purifier model 18155 and it worked great two days. We went out of town for one night, came home and the the thing wouldn't turn on. No lights, sound or anything! It wasn't even moved at all from the location where it was working just a day before. I wonder if we had a power surge or something that burned a fuse. I moved it to another outlet and still nothing. Any suggestions? I need clean air in my daughter's room; she has asthma.

Thanks!
Rick
