Whirlpool Microwave Error Codes: Complete List

Whirlpool Microwave Error Codes at a Glance#

Whirlpool documents 46 error codes for its microwaves, and this page carries all of them. Six come with a full documented diagnosis — a stated cause and a procedure — and the other forty come with a one-line description of what the control detected and nothing more. That gap is the most useful thing to know before you start reading, because it decides how much the code alone can tell you.

Read the code set as a whole and it tells you something else. Hood and vent-fan faults, a convection thermistor, a magnetron temperature thermistor, a gas sensor and pre-heat codes all sit in the same table — the signature of an over-the-range or combination microwave-oven rather than a countertop unit.

Whirlpool Microwave Error Codes#

The Whirlpool microwave index lists all 46 documented codes at /error-codes/whirlpool; the table above covers the 6 with a full documented diagnosis.

How to Read a Whirlpool Microwave Error Code#

Start with the table above, then be clear about what it is: the six codes carrying a full documented diagnosis are three connectivity faults, each documented twice — once with a space (FC E1), once without (FCE1). All six mean the appliance could not reach the router. That is useful if your microwave has stopped talking to your phone and silent on anything to do with cooking.

The other forty are where the appliance actually lives, and they group by subsystem far more usefully than they sort alphabetically.

Temperature sensing is the largest group and what I check first, because a microwave that is guessing at temperature misbehaves in ways that look like everything else. F3T4 is the magnetron temperature thermistor, F3T3 the hood, F3T2 the convection thermistor, F3T1 the one behind the user interface. F3C and F4E1 both point at the cavity temperature thermistor, F3H and F4E4 at the humidity thermistor, F3H1 at the humidity sensor itself. Every one is documented the same way — a problem with that part or with the wiring associated with it — and the wiring half is worth ruling out first. A connector that has spent years directly above a range runs hot, and a tired harness reads exactly like a dead sensor.

Oven-side heat covers E13 and E23, where pre-heat did not complete; E24, an overheat limit reached; E61, E62 and E63, the oven sensor circuit reporting open or shorted; and E21 and E22, those same two conditions on the thermal sensor.

Gas sensing is E11 and E12 — a group most microwaves do not have at all.

The panel is E03, F2, F2E1 and F2Q1: the keypad or user interface reporting a problem, or the wiring to it.

Venting is F2H1 and F2H2, both the vent fan and light switch on the lower left front panel, plus a separate code that simply asks you to confirm the upper vent door opens and closes freely.

Then a group worth naming for what it does not say. F1E1, F1E4, F6, F6E0, F7, F8E5, F9 and F9Q1 are all documented as the oven being unable to execute the function — a placeholder, not a diagnosis. F9Q is more honest still: its documented text is that you may need assistance from a qualified technician. Demo Mode, SE and the Registration Error are not faults at all; the first is a showroom setting, the last a mis-entered registration number.

One thing the table cannot rank for you: every code in this data set is documented at the same severity and as homeowner-clearable. Treat that column as a formality here and judge by subsystem instead.

Which Whirlpool Microwave Codes You Can Clear Yourself#

Whirlpool's documented procedure for nearly every one of these is the same: cut power at the circuit breaker for one full minute, restore it, watch the display for a minute, then verify the microwave runs. One procedure, forty codes — which tells you what it is. It is a test of whether the control was merely confused, not a repair.

It does genuinely clear a control holding a stale state. It does nothing for a failed thermistor, and it cannot re-seat a connector.

Worth your own time: the connectivity codes, which are usually settled at the router rather than the appliance; the vent door, which you can physically check for free movement; and Demo Mode, which is a keypad sequence rather than a fault.

Not worth it: anything in the temperature-sensing or gas-sensing groups. Those need the part and its harness measured, and on an over-the-range unit that means bringing down an appliance mounted above a working range. If the panel reports an overheat limit or a magnetron temperature fault, stop using it and book the visit — those are the set's stop-now codes. Whatever the code, do not open the case: a microwave holds enough stored electrical energy to be dangerous long after it is unplugged.

When a Cleared Code Comes Straight Back#

A breaker reset clears the display because the display was holding the state. It does not clear the condition that produced it. So a code that returns within a cycle or two is not a stubborn code — it is a fault being re-detected, and that return is itself the diagnosis.

The distinction is worth most in the group documented as the oven being unable to execute the function. Those eight say almost nothing alone, but one that comes back immediately after a full power-down has narrowed itself considerably: the control is finding the same problem every time it looks.

Before booking, write down the code exactly as printed — the space matters, since FC E1 and FCE1 are documented separately — what the microwave will and will not do, and whether the code appears at idle or only during a cycle. Three lines, and they routinely save half a visit.

Whirlpool Microwave Error Code FAQ#

What does FC E1 mean on a Whirlpool microwave?#

That the appliance could not connect to the router. It is a network fault: the microwave heats and runs its cycles normally, and only the connected features stop working.

Is a microwave showing FC E2 worth repairing?#

Almost always, because the likely causes cost nothing to rule out — a connection time-out, weak signal strength, or a router that has quietly stopped accepting new connections. Only when the fault traces to the Wi-Fi module or its wiring does it become a parts decision.

How urgent is FC E3 once the panel shows it?#

Not urgent. Nothing inside the cavity has failed. Contrast it with a magnetron temperature or overheat code, which should stop you using the appliance that day.

Can FCE1 be cleared without opening the cabinet?#

Yes. A one-minute power-down at the breaker followed by a router reset clears most of them, and nothing in that sequence requires opening anything.

How do I reset a Whirlpool display after the fault clears?#

Cut power at the circuit breaker for one full minute, restore it, watch for a minute, then run a short cycle to confirm. Give it the whole minute — a quick flick of the breaker leaves the control holding exactly what it had.

Which of these codes can a homeowner safely handle?#

The connectivity group, the vent door check and Demo Mode. The sensor and gas-sensing groups need measurement at the part and its harness, which is technician work on a unit mounted above a range.
