Whirlpool RB220PXK0 electric built-in oven Parts

A failing Whirlpool oven control board on model RB220PXK0 typically shows up as a dead or flickering display, buttons that do not respond (or respond randomly), error codes, or heating that is erratic (no heat, intermittent heat, or overheating). These symptoms often come and go as the board heats up during use.

Common symptoms you can expect

• Display is blank, flickers, or resets like the oven is losing power
• Keypad inputs do nothing, beep continuously, or trigger the wrong function
• Oven will not bake or broil, or it starts heating then shuts off
• Temperature is unstable (runs too hot or too cool) even after preheat
• Error codes appear repeatedly, especially during or after a high-heat cycle
• You hear relays clicking rapidly, or you do not hear the normal relay click when a function is selected

Quick checks before blaming the control board

Because a control board depends on solid power and good heating circuits, we check these basics first (power off at the breaker before inspecting wiring):

• Confirm the breaker is fully reset (off, then on)
• Look for a burned or loose connection at the terminal block WP8203546
• Inspect the harness for heat damage; repair with high-temp wire such as cooking appliance 14-gauge splicing wire, 200-degree c (red) 242831 when needed
• If the oven does not heat at all, inspect and test the range bake element WP308180
• If the oven light is out, replace the light bulb 8009 (this is separate from heating, but it helps confirm the cavity is getting power)

Symptom-to-likely-cause guide

Symptom	More likely	Also check
Blank display, random resets	Control board or power feed issue	Terminal block, wiring connections
No heat in bake	Bake circuit issue	Bake element, wiring, control output
Overheats or swings widely	Control logic or sensing issue	Wiring, temperature sensing circuit
Buttons do not respond	Keypad/control issue	Loose ribbon/connector, power resets

Why it matters

A bad control board can prevent safe, accurate temperature control. Catching it early helps avoid repeated shutdowns, overheating, and damage to wiring connections and high-heat components.

On the Whirlpool RB220PXK0 electric wall oven, replacing the control panel typically means shutting off power, pulling the oven partially out of the cabinet, then removing the top/front cover to access the control area and transfer the wiring one connection at a time.

Before you start (safety and prep)

• Turn off the breaker to the wall oven (double-pole 240V circuit) and confirm the display is off.
• Let the oven cool completely.
• Protect the floor and cabinet edges with cardboard or a blanket.
• Have a second person help support the oven as you slide it out.
• Take photos of every wire connection before you move anything.

Basic steps to access the control panel area

These steps cover the common built-in Whirlpool wall oven layout used on RB220PXK0-STYLE units.

1. Shut off power at the breaker.
2. Open the oven door and remove the mounting screws that secure the oven to the cabinet (usually along the side trim).
3. Slide the oven forward a few inches to a foot, just enough to reach the top/front control area.
4. Remove the top cover or control cover (commonly held by multiple screws) to expose the control panel components.
5. Label and move wires one at a time from the old control panel/control components to the replacement.
6. Reassemble covers, slide the oven back, reinstall mounting screws, then restore power and test.

What parts are commonly involved

“Control panel” can mean different parts. Use this quick guide to match the symptom to the likely component.

Symptom	Most likely area	What to check first
Knob is cracked, loose, or missing	Knob/dial	Replace the knob or dial
Oven light does not work but oven heats	Light circuit	Replace bulb, check socket/wiring
No heat or intermittent heat	Heating circuit	Test bake element and wiring

Relevant parts for RB220PXK0 that we commonly see tied to control-area service:

• Control knob WP3150371 (if the knob is the issue, not the panel)
• Oven dial WP311069 (if the dial face/indicator is damaged)
• Light bulb 8009 (if the “panel problem” is actually no interior light)

Why it matters

A wall oven control area has multiple live circuits and tight wiring space. Sliding the oven out carefully and transferring wires one at a time prevents miswiring, nuisance breaker trips, and repeat failures.

An electric oven like the Whirlpool RB220PXK0 is built around heating components (bake and broil), temperature control parts, lighting, wiring connections, and the door hardware that seals heat in. The exact mix varies by model, but these are the core parts you will see most often.

Main parts you will typically find

• Bake element: the lower heater that does most baking (example: range bake element WP308180)
• Broil element: the upper heater for broiling and top browning
• Oven light and lens: illuminates the cavity (example bulb: light bulb 8009)
• Controls: knobs, dials, and internal control components that set temperature and mode (examples: control knob WP3150371, oven dial WP311069)
• Wiring and connections: carry power safely to heaters and controls (examples: terminal block WP8203546, cooking appliance 14-gauge splicing wire, 200-degree c (red) 242831)
• Door hardware: helps the door open, close, and seal properly (example: hinge pin WP307986)
• Insulation: helps hold heat in the cabinet (example: insulation WPW10208653)

Quick “what it does” guide

Part group	What it does	Common symptom when it fails
Heating (bake/broil)	Produces heat for cooking	Slow preheat, uneven baking, no heat in one mode
Controls	Regulates temperature and functions	Wrong temp, won’t switch modes, inconsistent results
Light	Lets you see food without opening door	No interior light
Power connections	Delivers power to the oven safely	Intermittent power, burning smell at connections
Door hardware/seal	Keeps heat inside the cavity	Heat loss, longer cook times, poor browning

Why it matters

Knowing the major oven parts helps you troubleshoot faster. For example, “no bake but broil works” usually points to the bake circuit (often the bake element), while “no power” can point to a power connection issue at the terminal block.

Ordering the right part for RB220PXK0

• Match your model number RB220PXK0 before ordering
• Compare the failed part’s location and mounting style
• Replace damaged connectors when replacing a heater
• Use the parts list for this model first, then search by model on Sears PartsDirect
