Kenmore Wall Oven 790.41003603 (79041003603, 790 41003603) Parts

This control mounting hex nut secures the burner or oven control to the control panel, keeping the shaft stable so the knob turns smoothly and the switch stays properly aligned.

• Threads onto the control/infinite switch or thermostat bushing to fasten it to the panel
• Prevents the control from rotating or shifting when the knob is turned
• Replace if the original nut is missing, stripped, rounded, or corroded
• Common signs: loose or wobbly knob, switch spins in the panel, or misaligned knob indexing

• Disconnect power; for gas appliances, also shut off gas before servicing
• Pull off the knob and any trim; support the control body from behind the panel while removing/installing the nut
• Start the new nut by hand to avoid cross-threading; tighten snugly with the correct-size wrench—do not overtighten
• The control sits square in the panel and the knob operates smoothly before restoring power

The Control Board is an OEM part for Frigidaire ovens. It is an integral electronic component responsible for operating various functions of the oven such as temperature controls, timers, displays, and sensors. The control board works behind the scenes to ensure reliable and consistent cooking performance. 

Causes of a bad control board can include exposure to excess heat over time, damage from electrical surges, or failures in electronic components. 

Symptoms of a bad control board include:

• Lights or displays not working properly 
• Inability to control temperature or time settings
• Unexpected shutdowns or failure to operate as directed
• Error codes appearing on the display

This OEM Frigidaire replacement part is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models. Installation is recommended by an experienced technician.

This oven heating element replaces a failed bake element to restore even, reliable oven heat for baking and roasting. It's a direct-replacement style part that heats the oven cavity when the bake function is used. What it does

• Heats the oven cavity during bake cycles so food cooks evenly
• Commonly used when the oven won't reach or hold baking temperatures
• Can fail visibly (broken or burned) or electrically (open circuit)
• Works with the oven's temperature control to maintain set temperature

• Disconnect power at the breaker before starting any repair to avoid shock.
• Handle the element carefully; connectors and terminals can be fragile.
• Confirm wire terminal fit and secure mounting; replace only with the correct OEM-style element.

Evaporator fan motor that circulates cold air over the evaporator coil to help maintain even refrigerator temperatures. Replacing a failing motor restores airflow, reduces warm spots and frost buildup, and cuts down on excessive fan noise. What it does:

• Spins the evaporator fan blade to move cold air through the evaporator and into the cabinet.
• Promotes even cooling to prevent warm zones and food spoilage.
• Stops or reduces abnormal noises caused by a worn or seized motor.
• Helps prevent frost accumulation linked to poor airflow.

• Disconnect power to the appliance before beginning any repair.
• Handle the motor and fan blade carefully; ensure the fan blade is seated properly on the shaft.
• Remove evaporator/fan housing panels and retain screws and clips for reassembly; verify wiring connectors match before reconnecting.

The Convection Relay Board is an OEM part for Frigidaire ranges. As a specialized electronic component, it seamlessly powers the convection fan and heating elements facilitating enhanced bake modes.

Prolonged electromagnetic interference exposure from convection fan motors degrades functionality over time reducing useful life without replacement. Versatile air circulation cooking depends on consistent control response.

Causes relate to normal electromagnetic component fatigue from field induction multiplying across years of regular convection cooking cycles. Impacts introduce risks abruptly limiting advanced airflow recipes. 

Symptoms indicating relay board issues involve:

• Fan failing to start or run continuously as needed
• Inability to sync convection modes with lower/upper element operation
• Error codes and non-responsiveness during convection preheat 

Replacing with this OEM Frigidaire part restores air movement management. Compatibility also fits some Electrolux, Gibson, and Kenmore ranges.

This spacer sets the correct gap between mating parts in your appliance's assembly, preventing rubbing and misalignment. Replace a missing or worn spacer to restore a solid fit, reduce noise, and protect surrounding components.

• Maintains proper spacing between components for correct alignment and operation
• Reduces metal-to-metal contact, squeaks, and premature wear
• Helps fasteners and panels seat securely
• Typical symptoms when failed: loose or rattling parts, uneven gaps, or visible wear marks

• Disconnect power; for gas models, shut off the gas. Allow the appliance to cool completely.
• Access the assembly per your model's diagram; note the original orientation/stack-up before removal.
• Reuse original fasteners if serviceable; hand-start threads and tighten snugly to avoid damaging the spacer.
• Verify alignment and clearances before fully reassembling. Quantity and location vary by model.

This heat-resistant insulation helps contain oven heat and shield surrounding components. Replacing worn insulation supports faster, more consistent preheating, steadier baking temperatures, and cooler exterior panels for safer, more efficient operation. What it does:

• Wraps/lines the oven cavity or panels to reduce heat loss and protect nearby wiring and controls
