How We See It
Living with a 790.4802 is the steady background baker — weeks of light duty, then Thanksgiving asks for everything at once. Self-cleaning with electronic temperature controls and a large window; Elite trims added convection for more even baking. Parts follow Frigidaire channels, which matters when a control board or element needs replacing. Day to day, spare the self-clean cycle before big cooking days and treat the door hinges kindly; heavy self-clean use ages the parts that matter. Parts are thinning and repairs route through the brand's network — price a big repair before you commit. Our data puts the ApplianceEdge Expected Lifespan at 15 years for this family. Treat that as the planning baseline, not the ceiling — well-maintained units regularly run past it.

Recurring Issues to Watch For
No documented programs or service records are on file for this platform. These are common wear points for the category.
Oven will not heat or takes much longer than it used to
Oven temperature is wrong or food cooks unevenly
Display is dead, oven resets, or shows repeated error codes
Convection fan is noisy, does not run, or baking is uneven
Broiler does not heat or only part of it glows
Door will not close, drags, or falls open
Oven is locked, will not unlock, or self-clean will not start
Oven shuts off while cooking or the cooling fan keeps running
Interior light does not work or the oven thinks the door is open
Glass is cracked, shattered, or the door becomes dangerously hot
Maintenance Habits
Keep the oven vents unobstructed.
Check before every use — Wall ovens rely on designed airflow to cool electronics and release cavity heat. Foil, towels or stored pans near the vent can overheat the control area.
Remove racks and accessories before self-clean and inspect the door gasket without scrubbing it.
Every self-clean cycle; gasket glance monthly — Self-clean can damage rack finishes, while abrasive cleaning can weaken the heat seal. The manual’s preparation protects the lock, gasket and rack system.
Spot-clean spills after the oven cools instead of letting them rebake.
After significant spills — Carbonized grease smokes, absorbs heat and demands harsher cleaning later. Early removal protects enamel and door seals.
Habits like these tend to extend the useful life of the appliance. They are not a guarantee against failure.
Kenmore's service story is clearer than people expect: Sears Home Services still runs a national repair operation that knows these machines, and parts stay easy through the same channels as whoever built yours.
Kenmore repair runs through Sears Home Services — still a real, operating national fleet, booked online, by phone, or chat. Out of warranty there's a second path: the model number's prefix tells you who actually built your machine (Whirlpool, LG, Frigidaire, Bosch), and any tech who knows that builder can service it with the right parts.

This page draws on the ApplianceEdge Registry — 2,640 appliance families connected to more than 18,200 verified models, independently researched. We don’t know everything about this family yet, and we won’t pretend to: finish records, filter and accessory cross-references, and warranty information for this platform are still being verified. We only publish what we can stand behind, and the gaps close as the Registry grows.
ApplianceEdge assessments — lifespans, repair values, and reliability notes — are our editorial opinions, built from documented third-party sources: owner reports, industry pricing data, manufacturer literature, and official records. They describe patterns across a product family, not any individual machine; your experience may differ. Recall information links directly to official CPSC notices. We accept no payment from manufacturers, and no brand influences what we publish.
