Im on my 2nd big buddy and both of them the fan has gone out, the first on went in a week, and this one last a couple of months.
1. oil the bearings,sae 30 or wd40 for places you cant get into.
dont take fan motor apart unelse you realy have to.
dont let your fan motor bearings get worn egg shaped from lack of oil.
2. make sure fan blades not hitting or scraping fan housing and fan blades are securely fastened to fan motor shaft.
3.mr heater fan motor is 12 volts DC , so it may have a segmated comutator and brushes.
I dont know because i have not yet needed to take my mr heater
fan motor apart but i have worked on hundereds of ac fan motors
in the past 65 years.
4. keep fan motors from getting wet. they hate water.
5. keep fans clean, they dont like foriegn materials.
Your specific problem: first fan 2 weeks,second fan 2 months.
how much you use them, are you wearing the brushes down?
Getting fan motor wet? foreign material getting pulled into fan or fan motor? off/on switch work ok. batterys good,battery contacts ok? fan transformer 110 vac to 12 vdc good? fan bearings oiled?
need more info to diagnose properly.
all of the above needs to be checked out to tell whats happened.
fan & fan motor needs to be inspected.
