Dayton 3ug73d just stopped working

220 - 240 volt, 60 hertz, properly grounded circuit with 40 amp breaker or fuse protection with #8 gauge wire. For Electric Heaters.

Grainger had a wide variety of bearings ... usually, they have a price spread for bearings depending on the quality of the bearing. I just ordered a $10.00 bearing for my $50.00 sander. They offered the same size bearing from another manaufacturer for $75.00. I didnt buy that one.

Good luck with your repair.

Here is your manual: http://www.air-n-water.com/manuals/G73.pdf

Around oklahoma, dirt dobber nests freezes up every things. Eyeball this and oil all frozen parts.

Check for loose or disconnected wire especially to the hi-limit switch or fan switch.

If its still under warranty I suggest you sort it that way. If its out of warranty I wouldnt bother with it, once these parts wear it is cheaper to buy another printer. Sorry to be the bearer of bad new, I hope this helps.

its most likely dirt/rust in your burner assy , but as its 15 year old and propane do your self a favour and get it inspected by a registered gas/propane engineer .
ive witnessed propane explosions at first hand and they are scary

is this a baseboard unit? the thermostat kit has four wires - a black and a red, a black and a red. for 240 volt operation, both line wires go on the two blacks and the heater load goes on the red wires

need to check you fan wires, some have differant colors on the moter for the differant speeds, you may need to change the fan speed by unplugging one of the wires and replacing it with another. hopefully you still have the manuel , check with it first!!!
