so i have the old ones off my furnace..they look the same but they say f150 on the bottom..would they still fit?

They should. Many snap discs are sized the same, but the on off range can be different for different applications. Some are even adjustable. I have two different discs on my wood furnace.

does this work with model 36dv?

I belive that it works on 110Ac as weel it would be more an aperage limit. They are very small therefore I would not think that they work control more than a 2 amp load. Good luck! P.S. I do find the temerature rating is great this unit cycles just fine on my wood stove fan.

Will this work on a 12V system?

it is a termo switch that closes the circuit on temprature rise. It can handle 120 Volts therefore 12 volts will be much less. Again it is just a switch!!

Is it hard for seller to specify degree symbol this way, cut-in 110°F (43°C) cut-out 90 deg. F (32 deg. C? Stating the word degree only, seriously?

How else would you like them to state their range of operation? What are you looking to accomplish?
