Getting a Newcastle furnace to keep heating
The house was getting cold, and the gas furnace was trying to light without keeping the heat on. For this Newcastle homeowner, the immediate need was straightforward: find out why the furnace could not stay running and get useful heat back into the home. The answer involved two separate checks during the same visit.
Starting with the blocked drain
Our technician found that the furnace was not maintaining the signal it needed from its exhaust safety system. Testing traced that first problem to a clogged condensate drain. We flushed the drain and cleared the obstruction so the furnace could move through its startup sequence.
With that blockage cleared, the furnace began to run. We kept watching it rather than ending the check at ignition. After about five minutes, it shut down again, this time on a high-limit code. The second stop showed that clearing the drain had addressed only part of the heating problem.
Checking for a sustained burn
Further testing led to an adjustment of the fuel pressure into an acceptable range. After the adjustment, the technician was able to maintain the burn, and the furnace was functional at the end of the visit.
That sequence mattered for the homeowner: the goal was heat that continued beyond the first few minutes. Following the equipment through a longer run revealed the additional adjustment it needed. Continued maintenance was recommended, and the office was to contact the homeowner about a maintenance visit. The immediate repair and that next step both focused on keeping the heating system ready for use.
