i'm new to the forum/wood furnace stuff (though we had one in my childhoold home). my GF has an older clayton 7.1 wood furnace; the backplate says "july 1983". the stove has the problem of the fan running for around 30s then shutting off for quite some time (could be minutes or what seems like hours) even though the stove is fired and quite hot. (aside from not heating the house efficiently, i worry about the stove overheating. a legitimate concern??)
it has what looks to be a honeywell L4064 high limit switch; see pics below. (the clayton manual doesn't give part numbers; google helped me figure out it was a honeywell L4064.) i took the cover off and observed that the scaleplate sticks in places as the temp moves up or down (e.g. when i put the blower on manual, for example) then it'll suddenly jump, giving off broken/stuck spring sounds. this switch on this stove uses a 5" temp probe. i'm planning to replace it with the same model but the L4064 looks like it comes in many specifications. any advise on which one to get? or maybe there's a different/equivalent part to consider; i.e. a drop-in replacement that fits in the same size hole used by the current switch? many thanks.
