UL A/D error — microprocessor analog-to-digital fault

The most common cause of the F1-E2 error on a Whirlpool oven is control board microprocessor failure (~70% of cases); start with: power cycle.

What Does Error Code F1-E2 Mean on a Whirlpool Oven?

UL A/D error — microprocessor analog-to-digital fault.

F1-E2 is an internal control fault reported when the ERC's microprocessor cannot correctly perform analog-to-digital conversions through its upper-limit (UL) watchdog circuit. Because A/D conversion is how the board reads sensor voltages, a failure here means it can no longer trust any temperature or input signal. Unlike F1-E0 or F1-E1, which point to other control self-checks, F1-E2 isolates the A/D/watchdog stage — a defect internal to the board rather than a wiring or sensor problem.

Models affected: Whirlpool electric and gas ranges/ovens using an electronic range control (ERC), including models such as WFE525S0JZ and WFG320M0BS
What owners report: Owners commonly report this code appearing suddenly at power-up or mid-cycle, sometimes accompanied by beeping and an unresponsive keypad. A brief power cycle at the breaker occasionally clears a one-time glitch, but when F1-E2 returns it typically points to the control board itself rather than anything an owner can adjust.

What Causes Error Code F1-E2?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Control board microprocessor failure 70% of cases
  2. 2
    Power supply instability 20% of cases
  3. 3
    Internal board fault 10% of cases

How to Fix Whirlpool Oven Error Code F1-E2

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Power cycle

    Turn off circuit breaker 5 minutes.

  2. 2

    Replace the ERC board

    An A/D conversion fault is internal to the control board and not field-repairable.

    🔩 Whirlpool ERC board ($150–$380)
    ⚠️ Unplug oven before servicing.

How to Reset Error Code F1-E2

Turn off circuit breaker 5 minutes. If F1E2 persists, replace ERC board.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my Whirlpool Oven when error F1-E2 appears? +
It is not advisable. The oven may still power on, but running it while F1-E2 is active can worsen the control-board fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes F1-E2 on a Whirlpool Oven? +
Across reported Whirlpool oven repairs, the most frequent is control board microprocessor failure (70% of cases), power supply instability (20%), then internal board fault (10%). Check them in that order before replacing any parts.
F1-E2 keeps coming back after a reset — what should I check next? +
A reset only clears the stored F1-E2 fault; if it returns, the control-board problem is still present. Move on to the physical checks — power cycle, then replace the ERC board — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Whirlpool Oven error F1-E2? +
A DIY repair typically runs $150–$380 in parts, versus $200–$500 for a professional service call. Expect the work to take roughly 30–60 minutes.
Which Whirlpool Oven models show error F1-E2? +
F1-E2 is documented on Whirlpool electric and gas ranges/ovens using an electronic range control (ERC), including models such as WFE525S0JZ and WFG320M0BS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
