Decision: Why Your Boiler Keeps Locking Out
Before we can prevent a repeat, we need to understand why your boiler in Wigan's surrounding areas, especially older properties like the dense terraced streets around Ormskirk Road in Pemberton, is locking out in the first place. Common culprits include a dirty or worn ignition/flame-sense electrode, a failing ignition lead or spark generator, or even a gas supply issue. Sometimes, a blocked condensate pipe can cause a secondary lockout, or the air/gas ratio might have drifted on an unserviced unit. Each of these points to a maintenance or system health problem, not a random occurrence.
- Worn ignition electrode diagnosis
- Gas pressure check at appliance
- Condensate trap inspection
- Air/gas ratio analysis
