Oven failures split cleanly between gas and electric, and NYC apartments have a roughly even mix of both — with gas more common in pre-war Brooklyn brownstones and Queens attached houses, and electric more common in postwar towers and modern condos. Here's how to diagnose each.
Gas Oven Not Heating: Brooklyn and Queens
Igniter Failure — The Most Common Cause The igniter is the glow bar that heats to orange-red before opening the gas valve. When it weakens, it can no longer generate enough heat to open the valve's bimetal safety, so gas never flows and the oven never lights.
How to check: Turn the oven to bake and watch through the oven window with the light off. You should see the igniter glow orange within 60–90 seconds, then hear the gas ignite. If the igniter glows but the gas never ignites — or if the igniter barely glows at all — the igniter has failed.
Igniter replacement is a parts-and-labor job that runs $150–250 and takes under an hour. It's the most common oven repair we do across Brooklyn and Queens.
Gas Valve Failure If the igniter glows bright orange but still no gas ignites, the gas valve itself may have failed. Less common than igniter failure, but requires a licensed technician — gas valve replacement involves disconnecting and reconnecting a gas line, which requires proper certification in NYC.
Thermostat Calibration If your oven heats but the temperature is consistently off (food burns or stays underdone even with correct timing), the thermostat may need calibration. Most modern ovens allow user calibration through the control panel — check your manual. If calibration doesn't fix it, the temperature sensor or control board needs replacement.
Gas Safety Note for NYC Residents If you smell gas near your oven and the oven is off, do not attempt any diagnosis. Leave the apartment, prop doors open if safe to do so, and call Con Edison at 1-800-75-CONED. ProFix technicians are licensed for gas appliance repair in New York but will not perform work while there is active gas odor in the space.
Electric Oven Not Heating: NYC
Bake or Broil Element Failure Electric ovens have separate heating elements for bake (bottom) and broil (top). Either can fail independently. A failed bake element may cause uneven heating or no heat at all; a failed broil element usually goes unnoticed until someone tries to broil.
Visual check: Remove the oven racks and look at the bake element at the bottom of the oven. If you see visible breaks, blistering, or burn marks on the element — it's failed and needs replacement. Element replacement runs $100–200.
Control Board Failure Modern electric ovens controlled by touch panels or digital displays can experience control board failure that prevents the oven from heating even though the elements are functional. Signs include error codes on the display, buttons that don't respond, or the oven behaving erratically.
Circuit Breaker Electric ovens in NYC apartments run on a dedicated 240V circuit. If the oven has no power at all (clock is off, no display), check the circuit breaker panel. A tripped breaker will look slightly out of alignment compared to the others — reset it and test. If it immediately trips again, call an electrician before calling an appliance technician.
NYC-Specific Considerations
Older buildings with 60-amp service: Pre-war Brooklyn buildings that haven't had electrical upgrades sometimes have 60-amp total service panels. Adding a high-draw electric oven can cause repeated circuit breaker trips. This is a building electrical issue, not an oven issue.
Co-op restrictions on gas appliance replacement: Some NYC co-ops prohibit converting from gas to electric or vice versa due to building infrastructure. If you're replacing an oven, verify with your board before purchasing.
Slide-in vs. freestanding dimensions: NYC kitchens were built to specific cabinet depths that may not accommodate standard 30-inch slide-in ranges. If you're replacing an oven, measure the opening carefully — older Brooklyn kitchen cabinets often have non-standard depths.
