Kenmore 79046591504 electric range Parts

On the Kenmore 79046591504 electric range, the cooktop removal method depends on whether you have a lift-up top (common on coil-element models) or a ceramic glass cooktop; for cleaning access, many versions lift from the front and are held up by a support rod. Use the steps in the 79046591504 owner's manual to match your exact cooktop style.

Before you start (safety and prep)

• Turn off power at the breaker (240V range circuit), not just the control panel.
• Let all surface elements and the oven cool completely.
• Pull the range forward only as needed; avoid stressing the power cord.
• Protect the countertop and cooktop surface with a towel or cardboard.
• Do not lift or carry the range by the ceramic glass.

If your range has a lift-up cooktop (typical coil-element style)

The manual describes a lift-up top used for cleaning underneath.

• Grasp the cooktop at the front sides.
• Lift from the front only until the support rod can swing into place.
• Clean underneath with hot, soapy water and a cloth.
• To lower, lift slightly, fold the rod down, then lower the top carefully.

If your range has a ceramic glass cooktop (common smooth-top style)

For full removal, the cooktop is typically secured with fasteners and wiring.

• Remove mounting screws (often under the front lip or accessed after opening the oven door or removing a trim piece).
• Lift the cooktop slightly and support it; note wire harness routing before disconnecting anything.
• If you need to disconnect a radiant element, label connectors first.
• Reinstall by aligning the cooktop, routing wires exactly as before, and tightening screws evenly.

Quick comparison: lift-up vs. full removal

Cooktop type	What you can do without tools	What usually requires tools
Lift-up (coil)	Raise top for cleaning under it	Rarely needs full removal
Ceramic glass	Limited access without removing fasteners	Removing screws and managing wiring

Why it matters

Raising or removing the cooktop the right way prevents pinched fingers, damaged wiring, and cracked glass. It also helps you safely access surface element connections, spills, and debris that can cause heating problems.

To replace the oven control board on your Kenmore electric range model 79046591504, we shut off power, access the control area, move each wire and the ribbon connector to the matching spot on the new board, then reassemble and test basic Bake and Broil functions using the 79046591504 owner's manual.

Safety first (before you touch the console)

• Turn power off at the breaker (240V); confirm the display is dark.
• Let the range cool completely.
• Pull the range forward only as needed; avoid stressing the power cord.
• Use gloves; sheet-metal edges behind panels are sharp.
• Keep screws organized by location.

Replacement steps (typical for this Kenmore 79046591504)

1. Disconnect power at the main source.
2. Access the control area: remove the rear access panel behind the control console (or the paneling required to reach the electronic oven control).
3. Document connections: take a clear photo of every wire position and connector orientation.
4. Transfer wires one at a time from the old board to the new board (this prevents mix-ups).
5. Reconnect the ribbon cable: fully insert the ribbon into the connector, then lock/snap the connector into place.
6. Reinstall panels and secure all screws.
7. Restore power and verify operation (Clock, Bake, Broil). The installation instructions recommend checking oven element operation after installation or service.

Quick troubleshooting if it still will not work

• No display after replacement: recheck breaker, terminal connections, and that the ribbon cable is fully seated.
• Oven heats wrong: test the oven temperature sensor; a failed sensor can mimic control problems. Consider the frigidaire range oven temperature sensor 316217002.
• Bake or broil not heating: inspect the heating elements for visible damage; for bake issues, the frigidaire range bake element 318255401 is a common failure item.

What to check after reassembly

Check	What “good” looks like	What it points to if not
Display/clock	Powers up normally	Power feed, ribbon, board connection
Bake at 350°F	Heats and cycles	Sensor, bake element, wiring
Broil	Top element heats	Broil element, relay, wiring

Why it matters

The oven control board is the “traffic controller” for temperature sensing and element cycling. A single loose ribbon connector or swapped wire can stop heating or cause incorrect temperatures, so careful wire-by-wire transfer is the difference between a clean repair and repeat symptoms.

On the Kenmore 79046591504 electric range, an oven that “stops working” is usually caused by a power supply problem, a failed heating circuit (bake or broil), or a control or sensor issue that prevents the elements from turning red during Bake or Broil. Use the checks and test modes in the 79046591504 owner's manual to narrow it down.

Quick checks first (most common)

• Confirm the range has 240 volts at the outlet; a tripped breaker can leave you with lights but no heat.
• Make sure the oven is not in a power-failure state; if power flickered, turn the oven off, then reset.
• Verify the oven vent is not blocked; blocked venting can cause poor performance and overheating.
• Try Bake at 350°F and Broil; on this model, the lower element should glow red in Bake and the upper element should glow red in Broil.
• If the control is responsive but temperatures are wrong, suspect the temperature sensor.

What failed parts typically look like

Symptom	Most likely cause	What you’ll notice
No heat in Bake, Broil works	Bake element failure	No red glow from lower element
No heat in Broil, Bake works	Broil element failure	No red glow from upper element
Heats but temp is way off	Sensor or control issue	Overcooks or undercooks
Dead or intermittent operation	Loose/burned power connection	Heat cuts out, may smell hot wiring

Parts that commonly fix “no heat” on this model

• Frigidaire range bake element 318255401 (if Bake will not heat)
• Frigidaire range oven temperature sensor 316217002 (if temps are inaccurate or erroring)
• Terminal block 5304409888 (if the power cord connection is loose or overheated)

Why it matters

An electric range can appear “on” with only one leg of power, but the oven heating elements need full 240V. Catching a failing element, sensor, or terminal block early prevents repeated shutdowns and inconsistent baking.

For Kenmore electric range model 79046591504, the model and serial number are printed on the serial plate on the oven front frame behind the oven door; on some versions, the plate is behind the storage drawer. Use the exact model number when ordering parts.

Where to look on model 79046591504

Check these common label locations first:

• Open the oven door and look on the front frame (the frame around the oven opening)
• Look behind the oven door on the front frame near the edge
• Pull out the storage drawer and look behind the drawer opening (some models place the plate there)
• If the label is hard to read, use a flashlight and take a photo to zoom in

What to write down (and why)

Record the full information from the serial plate so you can match parts correctly.

• Model number (example: 79046591504)
• Serial number
• Lot number or letter (often printed near the serial)

Why it matters

Kenmore 790-series ranges can look similar but use different bake elements, surface elements, control parts, and wiring. The exact model number ensures you get the right diagrams and the right replacement part the first time.

Quick reference

What you need	Where it’s found	When you’ll use it
Model number	Serial plate behind oven door (or behind drawer on some models)	Parts lookup, manuals, compatibility
Serial number	Same serial plate	Service history, warranty, identification
Lot number/letter	Same serial plate	Parts inquiries and production variations

Helpful tip from the documentation

The installation instructions for this range specifically note the serial plate location on the oven front frame behind the oven door, or behind the drawer on some models. For diagrams and additional identification details, use the 79046591504 installation guide and the 79046591504 owner’s manual.

If your Kenmore electric range model 79046591504 isn’t getting hot, the most common causes are a failed bake element, a bad oven temperature sensor, or a power supply issue (one leg of 240V missing). Start with a visual check, then test the heating circuit components.

Quick checks first (fastest wins)

• Confirm the range is getting 240V at the outlet; if only 120V is present, the oven may not heat even though the clock and lights work.
• Make sure you are not in a delayed start or special mode; verify settings in the 79046591504 owner's manual.
• Look for obvious damage: a blistered, cracked, or separated bake element.
• Avoid lining the oven bottom with foil; it disrupts heat distribution and can cause poor baking results.
• If the oven was used during a power interruption, turn the oven off and restart the bake cycle.

Parts that most often cause “no heat”

1) Bake element

If the oven won’t heat in Bake, the bake element is the first suspect. A failed element often shows visible breaks, but it can also fail with no obvious damage.

• Test for continuity with a multimeter (power off).
• Check wiring terminals for overheating or loose connections.
• Replace if open (no continuity).

Model-matched part: Frigidaire range bake element 318255401

2) Oven temperature sensor

A sensor that reads incorrectly can prevent proper heating or cause long preheat times.

• Inspect the sensor harness connection at the back of the range.
• Test sensor resistance at room temperature (compare to the spec in the manual/service info).

Model-matched part: Frigidaire range oven temperature sensor 316217002

3) Control or wiring issues

If elements and sensor test good, the issue is often in the control circuit or wiring.

Symptom	Most likely area to check	What to do
Broil works, Bake doesn’t	Bake element circuit	Test/replace bake element, inspect wiring
Neither Bake nor Broil heats	Power supply, control, wiring	Verify 240V, inspect terminal block and connections
Heats sometimes, then stops	Loose connection, overheating	Check terminals, harness plugs, and signs of arcing

Why it matters

An electric oven needs full 240V and a complete heating circuit to reach temperature. A single failed component (element, sensor, connection) can stop heating, cause underbaking, or create unsafe overheating at terminals.
