CCB,I a huge Fan of Spares ! Usually,at the worst times,something usually craps out on you. As usual,all you have to do is wave your Magic Wand to create Spares Money! Your situation for how you heat is the Master on this issue. If you can suffer or live with your unit going down and staying down for,let's say,the duration of this coming Cold Snap,then you can hold back and expend funds when failure occurs. Most of us rely on our Coalburners. Most of us like to gain advice here on actual Motor Numbers,and what are Proprietary(Dealer or Factory Only Available)Parts. It's a great practice to gear up(no pun intended)for what's ahead by doing it in a calm time when all is well! Things like knowing where our unit manual is,or can it be downloaded and printed online. Do we need any tooling to make that 0330 A.M. Gearmotor changeout any easier. Lastly,having Critical Spares on the Shelf at Home sure keeps the most hair on the top of your head! It took a lot to get to where you are. See if you can secure your position and start making plans to self-support your Coalburner...Good Luck on what You Decide!
