Kenmore 7909421240B electric range Parts

On Kenmore electric range model 7909421240B, the model and serial number are printed on the identification (serial) plate located on the right side of the oven front frame, inside the storage drawer or warmer drawer compartment. The quickest way is to pull the drawer out and look along the right front frame. See the 7909421240B owner's manual for the exact plate location illustration.

1. Turn the range off and let it cool.
2. Pull the storage drawer or warmer drawer straight out.
3. Look on the right side of the oven front frame (the metal frame just behind the drawer opening).
4. Record both the model and serial numbers for parts lookup and service.

• Inside the storage drawer or warmer drawer opening (right front frame)
• Behind the lower panel (on some versions)
• Back of the range near the vent area (less common for this model family)
• Door jamb area (more common on some ovens, but the drawer area is the primary spot for 790.9421/9422 models)

The plate usually lists the model in a format similar to 790.9421 (with additional digits/letters for the full model, such as 7909421240B) plus a serial number.

Kenmore ranges often have multiple versions that look identical. Using the exact model number prevents ordering the wrong surface element switch, oven temperature sensor, or control overlay.

To reset your Kenmore electric range model 7909421240B, turn the range OFF, shut off power at the breaker (or unplug it), wait 1 minute, then restore power and reset the clock and any oven settings. This clears many control glitches after a power interruption.

• Turn all surface burner knobs to OFF.
• If the oven is running, press Cancel/Off first.
• Switch the range circuit OFF at the household breaker (preferred) or unplug the cord.
• Wait 60 seconds.
• Restore power.
• Set the clock, then test Bake and a surface element.

If the door is locked, do not force it. Let the oven cool for about 1 hour until the lock light goes out, then open the door normally and retry the reset.

Your 7909421240B can resume operation when power returns if it was left on. Turning the range off and doing a controlled power reset helps prevent unexpected heating and restores normal control operation. For model-specific control and clock steps, use the 7909421240B owner's manual.

On the Kenmore 7909421240B electric range, an oven that “stops working” is usually caused by a power problem (outage, loose cord, tripped breaker) or a failed heating or control component such as the bake element, broil element, oven temperature sensor, or an electronic control issue. See the 7909421240B owner's manual for model-specific checks and control settings.

• Confirm the range has power; check house lights and reset the range clock after power returns.
• Verify the cord is plugged in securely and the outlet is working.
• Check the home circuit breaker(s) for a trip (ranges often use a 240V double breaker).
• Make sure the oven controls are set correctly for Bake or Broil.
• If the oven was in Self-Clean, wait for it to cool; the door can stay locked for about 1 hour after the cycle.

If power is good but the oven will not heat or heats poorly, these are the most frequent culprits:

Model-matched parts you may need include the frigidaire range oven temperature sensor 316490000 and the frigidaire range bake element 316413800.

When an oven stops working, starting with power and control settings prevents unnecessary part replacement. If power is restored after an outage, the range can resume operation; turning controls off and resetting the clock helps you return to safe, predictable operation.

• Do not attempt to operate the range during a power failure.
• After Self-Clean, do not force the door open; wait until the lock light goes out and the oven cools.

On the Kenmore 7909421240B electric range, there is not a single, user-accessible “fuse” you can point to like a plug-in cartridge. The most common safety device people mean is a thermal limiter/thermal fuse, which is typically mounted on the rear of the range or on/near the oven cavity wiring, and it is accessed by removing the back panel; use the 7909421240B owner's manual for your model’s access and safety steps.

• Unplug the range or switch OFF the double-pole breaker before any inspection.
• Confirm the issue: dead display, oven not heating, or surface elements not working.
• Check the home electrical supply: a range needs 240 VAC (two hot legs); a tripped breaker can leave you with partial power.
• If only the oven is acting up, check the oven temperature sensor and heating circuit.
• If only one surface burner is acting up, focus on that burner’s switch and receptacle.

Most Kenmore 790-series electric ranges place the thermal limiter/thermal fuse in one of these spots:

If your problem is heat-related rather than total power loss, these parts are frequent suspects:

• Frigidaire range oven temperature sensor 316490000 (helps regulate oven temperature)
• Frigidaire range bake element 316413800 (primary oven heating element)
• Frigidaire range broil element 316203301 (top heating element for broil)
• Range surface element receptacle 5303935058 (burner connection block)

A blown thermal fuse/limiter or an overheated wiring connection can shut down heating (or the whole range) to prevent damage. Finding the correct device location and testing it with power disconnected helps you avoid replacing good parts and restores safe operation.
