My furnace has a Honeywell R8182D Aquastat. The furnace has been trying to ignite but fails after 3 or 4 trys. The 2K relay clicks on and off or buzzes. The furnace will start and run if I manually hold the relay in its run position. All other furnace components check out, new filter, good oil, electrodes, nozzle clear, transformer holds a spark up to about 3/4 of an inch when jumped across the contacts. Is it time for a new Aquastat, or can the relay be changed itself?
