The Honeywell is a very good control. The blue johnson control is pure junk. The Johnsons had , I believe 11 updates to them over the years untill Lennox finally got honeywell to make the control. I have not seen a Honeywell fail in the 2 years or so that they have replaceded the Johnson. If anyone out there has a blue johnson control on their Lennox G23 or G26 furnace, you should buy a Lennox part no.53L90 as it is the new honeywell and keep it on hand. I have replaced several hundreds of the johnsons. It is not a matter if they will fail it is a matter of when!
