Dynatrap Mosquito Trap Fan Fix

Working mosquito trap after undocumented required maintenance.

• Screwdrivers
• Machine oil

Dynatraps or other appliances with fans can get gummed up with years of dirt and at some point will stop.

The motor is a standard 12v fan like a computer fan and is especially problematic with years of dirt or spiderwebs.

Fortunately it can be fixed with a drop of oil if it is just barely starting. DC motors have magnets around a circular axis and if it can't start - or is just doing a partial turn every time, it's due to friction.

The device fan grid can be pried off. As with most appliances of this type, undo all the screws, where there are no screws you can use a couple flat screwdrivers to push open and unclip the plastic clips keeping the fan assembly on.

The fan here is like the usual 12v computer fan - you will notice that under this sticker there is a rubber plug. Under the rubber plug there is the axle of rotation, and if you add a couple drops the motor will be un-bound!
