: Good thing there's a contract. Going to 5 seconds from 10 seconds isn't the right direction.
: As there are new ignition components; I'd suspect a change in the electrical grounding of the home and/or appliance. Problems of such nature are a 'ghost' that confounds for a long time.
: A moisture-clogged pressure switch tube is another of those difficult-to-find problems.
Update: it ended up being the high limit sensor. When the technician jumped the terminals, it ran fine. Sensor is on order. One other question....the operating temp is 180. we have a high fire control that I have switched to only run when outside temp is less than 20. What should that temp be set at for optimum economy? It would be the inlet water temp that causes high fire to come on. Currently is set at 160. Thanks
