Common quick fixes
Start here before you call — most issues are on this list.
| Symptom | Likely cause | What to do |
|---|---|---|
| Won't turn on | No power, tripped GFI, or cover not seated on the door safety switch | Check the receptacle/GFI and reseat the cover so the door switch closes. Check the main fuse. |
