I have a 5 tons Lennox G61MPV natural gas furnace. I also have a 5 tons Lennox G43UF natural gas furnace which I do not use anymore (but is in perfect working order). Both units are about 5 years old.
Would it be possible to take the blower motor and control board of the G43UF and use them in the G61MPV? In other words, the G61MPV would operate like a G43UF.
Btw, I know that the G61MPV is a variable speed dual-stage furnace. While the G43UF is a 'traditional' furnace.
Thanks for your help.
P.S. I suspect I would also need to use a different thermostat than the Lennox Signature Stat I currently use.
