01 · Door issues are mechanical
Most door issues are mechanical, not electrical. Hinges sag, glass cracks, gaskets compress flat, switches wear, locks jam. The diagnostic is largely visual plus measurement. The bigger picture: door problems often surface AFTER cooking inconsistency emerged. Heat loss from a sagging hinge or torn gasket means the oven runs longer to compensate, the customer notices uneven cooking before they notice the door is wrong.

02 · Hinge sag (year 7 to 10, most common)
Oven hinges carry the door weight and operate via spring-loaded mechanisms that wear with thermal cycling. Mid-market hinges $200 to $380 replacement (per pair). Pro-style hinges (Wolf, Viking, Thermador, BlueStar, Capital, Miele) $600 to $900 (per pair), heavier-duty spring assemblies for heavier doors and longer service-life expectations.
Symptom progression: door looks fine when fully closed, gap appears at top when partially closed, eventually visible top-corner gap at full close. Heat escapes through the gap, top of food cooks lighter than bottom, customer attributes it to "oven runs cold" or "uneven cooking" before noticing the door.
On double ovens, the lower oven hinges fail first and faster than the upper. The lower oven sees more heat from cycle convection, more weight on the door, and more open-close cycles in typical use (cooks reach the lower oven for everyday baking, the upper is reserved for entertaining or self-clean). By the time the lower hinges sag visibly, the upper is usually 60 to 80% along the same wear curve. We recommend replacing both pairs proactively on double ovens past year 8, $120 to $200 extra in parts cost saves a full second service call within 12 to 24 months.
03 · Door glass crack / spider damage
Cracked or shattered oven door glass cannot be repaired. The glass is tempered or layered with thermal-shock resistance properties that are lost the moment the integrity breaks. Even if the visible crack looks small, the structural rating is compromised, and continuing to use the oven risks the glass exploding outward at high temperature.
Replacement runs $300 to $560 for mid-market doors. Pro-style doors (Wolf, Viking, Thermador) run $700 to $1,200 because the glass is a custom assembly with brand-specific dimensions and sometimes integrated handle hardware.
Multi-pane debris (visible particles between two layers of glass) is a separate issue, debris doesn't get out without a full door rebuild, $1,100 to $1,800 on premium models.
04 · Door gasket / seal failure
The door gasket is a fabric or silicone-rubber seal around the door perimeter that compresses against the oven frame to prevent hot air from escaping. Year 5 to 8 typical wear pattern: gasket flattens at the corners, cracks along the top edge, or tears at the hinge side from repeated compression cycles.
Symptom: oven runs longer to reach setpoint, top of oven cavity runs cooler than bottom (hot air escapes upward through the gap), food browns unevenly. Often diagnosed during a "temperature off" call where the underlying cause is door seal, not sensor. Replacement gasket $180 to $340 with labor.
05 · Door switch and lock
Detects whether the door is open or closed. Used by oven light circuit (light comes on when door opens) and by safety interlock (oven won't operate without confirmed-closed door). Wears mechanically. Replacement $200 to $340.
Mechanical motor or electronic latch that locks the door during self-clean to prevent burns. When stuck after the cycle, see self-clean problems for the full diagnostic.

Composite examples; model numbers, ages, and prices are accurate to typical scope.
Customer complained of "oven runs cold". Visual inspection: top-right hinge sagged 12mm. Replaced both hinges as a pair (Wolf doors are heavy, single-side replacement creates uneven door weight). Tested door close, even gap restored, ran 350°F preheat test, setpoint reached in 11 minutes (was 18 minutes pre-repair). Total: $89 plus $640 hinges plus 1.5 hours = $780.
Owner reported "uneven baking, top is always lighter". Diagnosed: door gasket flattened at top corners, hot air escaping. Replaced gasket, ran multi-position thermometer test, top-to-bottom gradient flattened from 35°F to 8°F. Total: $89 plus $210 gasket plus 45 minutes = $290.
Door switch intermittent (oven light cycling on and off when stationary), plus minor glass crack at the bottom-right inner glass from a kid's impact. Replaced door switch, replaced inner glass panel. Total: $89 plus $475 parts plus 1 hour = $560.
Multi-pane debris on lower oven (visible particles between glass layers). Door rebuild required, parts ordered through BSH parts distribution (5 to 7 day lead). Customer also reported lower-oven hinge sag, which we recommended addressing on the same visit; replaced lower hinges proactively, upper hinges measured 70% wear, customer chose to defer upper replacement (will revisit at next service). Total: $89 plus $980 door rebuild plus $260 lower hinges plus 2.5 hours = $1,180.

09 · FAQ
Close the oven door fully and look at the gap between the door and the frame at the top corners. If one corner has a wider gap than the other, or both top corners gap evenly while the bottom is flush, the hinges are sagging. Healthy doors close with even gap all around (about 1mm). Sag of 5mm or more at the top corner is repair-needed; below that you're still in normal wear range.
Replaced only. Cracked or shattered oven door glass is not repairable, the safety properties (tempered, layered, or ceramic) are lost the moment integrity is broken. Replacement runs $300 to $560 for mid-market doors, $700 to $1,200 for pro-style (Wolf, Viking, Thermador) where the glass is a custom assembly.
Door switch (the small mechanical switch that detects door open or closed). Light always on means the switch reads door open even when closed; light never on means switch reads closed even when open. Either way the oven might also refuse to start, since most safety interlocks use the same switch. Replacement $200 to $340.
Yes. Pro-style hinges are heavy-duty spring assemblies that hold the weight of larger glass and heavier door panels. Replacement runs $600 to $900 versus $200 to $380 mid-market. Worth it because the door is meant to last 18 to 25 years, replacing hinges at year 8 or 12 keeps the rest of the oven on its design service life.
Related but distinct. The self-clean cycle locks the door for safety during 900°F+ operation; sometimes the lock motor or its electronic latch fails to release after the cycle ends. We cover this on /services/oven-repair/self-clean-problems/. The fix often overlaps (door lock motor replacement) but the diagnostic context is the cycle, not general door wear.
Yes, on most GE, KitchenAid, and Whirlpool double ovens. The lower oven hinges fail first and faster than the upper, because the lower oven sees more heat (rising heat from below cycles compounds), more weight on the door, and more open-close cycles in typical use. By the time the lower hinges sag, the upper are usually 60 to 80% along the same wear curve. Replacing both pairs in one visit costs slightly more in parts ($120 to $200 extra) but saves a full second service call within 12 to 24 months. We recommend it on doubles past year 8.
