Question about Hamilton Beach 31197 120 Watts Toaster Oven with Convection Cooking
You really need to replace the fan. This motor uses cheap sleeve bearings and you will only cause a problem (maybe burn the house down) trying to spray lube from the interior which I assume is what you are doing.
This is not an easy repair. I replaced mine which had an open winding. HB tried to make this unit so it could NOT be repaired, but of course it can be if you want to spend the time. The motor is part of a metal duct assy which also holds the rotisserie motor. It is RIVETED to the interior wall of the oven. The fan uses a DUAL shaft C-Frame shaded pole 120 VAC ~ 3000 RPM ~ .5 amp motor which is not very common, with 2 separate axial type metal blade sets. The oven door also develops a problem over time that keeps it from staying closed. The thermo on all these units is also inaccurate as the "sensor" is simply a metal plate screwed to the top right area of the oven interior. When I replaced my fan I also put in a new REAL oven thermo with a 12" sensing bulb which I mounted inside the oven as it should be. It took some searching to find these two parts. You can also repair the door mechanism at the same time and give yourself a couple more years until you have to do it again. I have all more and can post images if you want to tackle this. I did because the oven is large and the replacement model (31100 for $69 at Wal-Mart) has 1.5" less height and it uses the SAME parts with the same design flaw for the thermo. The retail cost on the parts for this job are ~$160, but I got mine for $15 total. I paid $48 for this oven years ago at Sams.

It seems to be a common occurrence with this type of toaster oven.
Do not use oil, that could give the possibility of it setting on fire or shorting out. If you must, try lubing it with over types of non-flammable liquids and tools.
I just want to make sure you are save when trying to handle this.
Another possibility is to return it and ask for a new one because of the defect.
