How to Fix F2 Error Code on Whirlpool WFG505M0BS (Gas Range)

by

I’ve been seeing F2 errors on Whirlpool’s WFG505M0BS come through my shop fairly regularly over the past several years — often enough that it’s one of those repairs I can practically do in my sleep. In probably 80% of the cases I’ve handled on this specific model, the culprit isn’t a failed sensor outright, but rather a cracked sensor probe or a corroded wiring harness connection at the back of the oven cavity — so that’s always the first thing I put eyes on before I even think about ordering parts. The F2 code does indicate an oven temperature sensor fault, meaning the control board is reading a resistance value outside its expected range, but don’t let that send you straight to the parts store until you’ve ruled out the simple stuff. If you’re comfortable with a multimeter and willing to take your time, this is absolutely a repair you can knock out in one to two hours at the kitchen table — and I’ll walk you through exactly how I’d approach it.

F2 Error Code

This guide walks you through diagnosing and fixing the F2 error code on the Whirlpool WFG505M0BS gas range. The F2 code indicates an oven temperature sensor fault, and most homeowners with basic mechanical skills can complete this repair in 1 to 2 hours without professional help.

Common Symptoms & Causes

The F2 error on this model typically presents alongside several recognizable symptoms before or after the code appears on the display.

  • F2 error code flashing on the control display during or after a bake or broil cycle
  • Oven overheating or failing to reach the set temperature accurately
  • Oven shuts off unexpectedly mid-cycle with the error code displayed
  • Control panel beeping continuously with no response to input

The most common root cause is a failed or out-of-range oven temperature sensor (RTD probe), though a faulty electronic oven control board can also trigger this fault code.

Safety First

  • Unplug the range from the wall outlet or shut off the dedicated circuit breaker before starting any work
  • Wear work gloves to protect against sharp metal edges inside the oven cavity
  • Photograph all wiring harness connections before disconnecting anything
  • Work in a well-lit space so you can clearly see wire routing and component placement

Tools & Parts Needed

Essential Tools

  • Phillips head screwdriver (#2)
  • Quarter-inch nut driver or socket set
  • Digital multimeter (for resistance testing)
  • Needle-nose pliers
  • Flashlight or headlamp

Step-by-Step Repair Instructions

🔨 Pro Tip from Dave

On the WFG505M0BS, the sensor harness connector sits behind the rear oven wall panel and has a known tendency to work itself loose from vibration over time — before you even pull the sensor, reseat that connector firmly and clear the code, because a loose connection will throw an identical F2 as a fully dead sensor and you don’t want to spend $30 on a part you don’t need. I’ve probably saved customers that exact part cost a dozen times just by catching this step first.

Step 1: Disconnect Power

Unplug the range from the power outlet or flip the dedicated circuit breaker to the off position. Wait at least five minutes before touching any internal components to allow residual heat to dissipate. Never skip this step, as the control board carries live voltage even when the range appears off.

Step 2: Locate the Oven Temperature Sensor

Open the oven door and look toward the upper left rear corner of the oven cavity. The temperature sensor is a thin metal probe mounted with two screws and connected to a wire harness that runs through the back wall. This is the most likely component responsible for triggering the F2 code.

Step 3: Test the Sensor with a Multimeter

Disconnect the sensor’s wire harness connector and set your multimeter to measure resistance (ohms). At room temperature, a good Whirlpool oven temperature sensor should read approximately 1,080 to 1,100 ohms. A reading significantly outside that range, or an open circuit reading, confirms the sensor has failed and must be replaced.

Step 4: Remove the Faulty Sensor

Remove the two Phillips screws securing the sensor bracket to the oven wall and gently pull the probe forward. Carefully feed the wire harness back through the oven wall opening, taking care not to damage the insulation. Set the old sensor aside for comparison with your replacement part.

Step 5: Install the Replacement Sensor

Thread the new sensor’s wire harness through the oven wall opening and seat the probe into the mounting bracket. Fasten the two mounting screws snugly but do not overtighten, as the bracket is thin metal that can strip easily. Reconnect the wire harness connector until it clicks firmly into place.

Step 6: Restore Power and Test

Plug the range back in and set the oven to bake at 350°F. Monitor the display as the oven preheats — the F2 error code should no longer appear if the sensor was the cause. If the code returns immediately or within a few minutes, the electronic oven control board likely needs to be replaced.

Step 7: Clear the Error Code

If the oven heats correctly without triggering F2, press the Cancel or Off button to clear any stored fault code from the control board memory. Some WFG505M0BS units require you to disconnect power for 60 seconds to fully reset the board and clear residual codes. After the reset, run a full bake cycle to confirm the repair is successful.

How Much Does This Repair Cost?

Replacing the oven temperature sensor yourself typically costs between $15 and $35 for the part. If the control board is also needed, expect to spend an additional $80 to $150 for the part. Compare that to a professional service call, which typically runs $150 to $300 just for labor and diagnosis on a gas range, and the DIY route saves most homeowners $100 to $250 or more on a straightforward sensor replacement.

When to Call a Professional

Most of the repairs in this guide are within reach for a careful DIYer with basic tools. In my experience, if you’ve replaced the temperature sensor, verified a solid harness connection, and the F2 code returns within a few cycles, the control board itself is likely misreading resistance values — at that point you’re looking at a board replacement that runs $150–$250 in parts alone, and improper installation can create gas ignition timing issues that make this a job for a certified technician. When in doubt, a diagnostic service call typically costs $80–$120 and can save you from a misdiagnosis that costs more in parts.

Frequently Asked Questions

The F2 error code on your Whirlpool WFG505M0BS points directly to a faulty oven temperature sensor, so that’s the first component you’ll want to replace.
