Gas boiler will not fire, keeps locking out, or heats intermittently in Newark? Call to describe the symptoms.

Local details that change the triage.
Newark's gas stock splits by ownership pattern more than by neighborhood. Campus-area rentals run older atmospheric gas boilers — standing or intermittent pilots, thermocouples, aging gas valves — often with thin maintenance histories. Owner-occupied colonials in College Park, Cherry Hill, and Nottingham Green run a healthier mix: mid-efficiency atmospheric units and modern sealed-combustion condensing units that have actually been serviced.
The practical difference: on a rental unit, the triage asks about service history first, because "unknown" maintenance plus an ignition fault usually means a burner overdue for cleaning, not a failed part. If you smell gas at any point, the gas utility's emergency line (or 911) comes before any boiler call, from outside the building.
What the local mix produces.
Newark's gas faults split by maintenance history more than by equipment type. On serviced boilers — mostly owner-occupied colonials — faults are textbook component wear: igniters crack, flame sensor rods coat with oxide, pressure switches drift, each failing singly and diagnosed with instruments. On long-unserviced boilers — disproportionately campus-area rentals — faults arrive as deferred-maintenance cascades: sooted burners, weakened igniters, and coated sensors failing together, where the real diagnosis is years without service.
Winter adds condensate freeze-ups on high-efficiency units: Newark's January nights in the teens and 20s can freeze exterior condensate drains, and a boiler that gurgled before dying overnight is describing exactly that. For the full technical breakdown, see our national gas boiler repair guide.
The fingerprints, with local context.
Pair each symptom with the unit's service history — Newark triage asks both:
Symptoms that narrow the diagnosis.
Newark's ignition faults split by maintenance history, and the pattern tells you which kind you have. On a serviced boiler, ignition faults are component end-of-life: a hot-surface igniter that finally cracked, a flame sensor rod coated after years of faithful firing, a pressure switch drifting out of spec. These fail one at a time, get diagnosed with instruments, and the unit runs on.
On a neglected boiler — and Newark's rental stock has many — ignition faults arrive as a crowd: sooted burner, weak igniter, coated sensor, tired gas valve, all degrading together. The symptom looks the same from the outside (lockout, fires-then-dies), but the diagnosis is years of skipped service rather than one failed part, and the fix is a full service plus whatever the neglect destroyed. Either way the safety rules are identical: one reset and observe, never repeated resets after a bang on startup — delayed ignition is a hazard — and a sounding CO alarm means leave the building and call 911.
Why campus-area units fail the way they do.
A gas boiler that has not been serviced in five years does not fail randomly — it fails predictably. Burners soot up, flame sensors coat, igniters weaken, and pumps seize, all on the maintenance schedule nobody followed. In Newark's rental stock this is the dominant failure mode: the unit is not defective, it is neglected, and the fix is service plus the parts that neglect destroyed.
For landlords, the takeaway is economic: annual service on a rental boiler costs far less than one January emergency call with tenants in place — and far less than the replacement that neglected units eventually force. Tenants: if your building's boiler looks like it has not been touched in years, that observation belongs in your written maintenance requests.
Straight answers before you call.
Igniter or flame sensor failure — the two wear items in every atmospheric and sealed gas unit. Note what you observe: clicking with no flame, a brief flame that drops out, or nothing at all. That observation, plus any error code on the display, is exactly what the triage needs when you call (888) 766-1474.
Replacement, not another cleaning — a sensor that will not hold a flame signal after cleaning is worn out. If a new sensor still drops out, the control board or the grounding path is suspect. Either way it is a technician visit; repeated cleanings on a dead sensor just postpone the fix.
It is losing water somewhere: a failed expansion tank that lost its air charge, a weeping joint in the loops, or a faulty auto-fill valve. Monthly refilling is not maintenance, it is a symptom — and every refill adds fresh oxygen that corrodes the system from the inside. Get the leak or the failed component found.
It wears it — constant up-down setting swings short-cycle the burner, stressing igniters and controls, and setback battles leave the system hunting. Locked thermostat covers are the standard landlord answer in student housing. If your rental boiler short-cycles, mention the thermostat situation on the call; it changes the diagnosis.
Usually a failed thermocouple or a draft problem — the pilot lights but the safety does not prove the flame, so the gas shuts off. It can also be a partially blocked flue. It needs a burner service visit; relighting a pilot that will not stay lit is not a homeowner fix.
