Whirlpool AC Error Codes: What We Can Confirm
Find your code, understand what it means, then run a guided diagnosis.
Error Code Finder
Look a code up against sourced manufacturer records. Codes we cannot source are not listed — a guessed meaning is worse than no meaning.
Whirlpool's residential AC documentation is the thinnest of any brand in our database. We could confirm five codes — E4, E5, E6, E7 and H6 — and no reliable source was located for E1, E2, E3 or the wider P and H series. Rather than borrow meanings from another manufacturer's table, we publish what is confirmed and name the gap, because a wrong code meaning is worse than a missing one.
What do Whirlpool AC error codes mean?
Of the codes we can confirm: E4 is a high-temperature, defrost or overload protection, E5 is an overcurrent, voltage or compressor overload protection, E6 is a communication error between the indoor and outdoor PCB, E7 is an indoor fan motor fault, and H6 is an indoor fan motor Hall-sensor or feedback fault. Other Whirlpool codes are not yet verified in our database.
Product families covered
-
Split / portable
The confirmed codes cover both split and portable units.
Where the code is displayed — and why it matters
The same fault can be labelled differently depending on which display you read it from, so identify the display before looking the code up.
- Indoor unit display
- Splits show the code on the front panel display.
- Portable unit display
- Portable units report the same E-code set on their control panel.
Whirlpool code prefixes
Only two prefixes appear in the confirmed set:
- E
- Protection trips, communication and fan motor faults
- H
- Fan motor feedback (Hall sensor) faults
How the families differ
- E7 and H6 are both indoor fan motor faults — E7 is the motor fault itself and H6 is the feedback signal from it, so they are related readings rather than separate problems.
- The confirmed set covers split and portable units together; our sources do not separate them, so no family-specific claim is made.
Confirmed Whirlpool codes
From a single independent compilation, so confidence is low. This table is explicitly partial — E1, E2, E3 and the wider P and H series were not located in official Whirlpool documentation.
| Code | What it reports | Applies to | Severity | Source |
|---|---|---|---|---|
| E4 | Is reported to indicate high-temperature / defrost protection, or overload protection (split and portable units) | Split / portable | — | C |
| E5 | Is reported to indicate overcurrent or voltage protection, or compressor overload | Split / portable | — | C |
| E6 | Is reported to indicate communication error between indoor and outdoor PCB | Split / portable | — | C |
| E7 | Is reported to indicate indoor fan motor fault | Split / portable | — | C |
| H6 | Is reported to indicate indoor fan motor Hall-sensor / feedback fault | Split / portable | — | C |
Before you act on a code
- This is an incomplete table. A code not listed here should be treated as unverified rather than matched to a similar-looking code from another brand.
- E5 covers overcurrent, voltage and compressor overload protection — leave the unit off and have the electrical side checked rather than resetting repeatedly.
- A dedicated pass against official Whirlpool service manuals is still needed before this brand can be considered fully researched.
Secondary source only
How to identify your system
- Note the exact code and whether the unit is a split or a portable.
- Note where you read it — indoor display or portable control panel.
- Photograph the unit's model label before contacting a technician.

Whirlpool error codes — common questions
What does Whirlpool E6 mean?
E6 is a communication error between the indoor and outdoor PCB. The fault sits in the interconnecting wiring, the terminations or the boards at either end rather than in the cooling circuit. One power cycle is reasonable; a code that returns needs inspection.
What is the difference between Whirlpool E7 and H6?
Both concern the indoor fan motor. E7 reports a fault in the motor itself, while H6 reports a Hall-sensor or feedback fault — the board is not receiving a valid speed signal. In practice both point a technician at the same assembly.
Why isn't my Whirlpool code listed?
Because we only publish codes we can source. Whirlpool's residential AC documentation is less available than most brands', and E1, E2, E3 and the wider P and H series were not reliably located. Send us the code on WhatsApp and we'll tell you what we can from the unit's behaviour instead.
Need this looked at properly?
Call or send a photo on WhatsApp and we will tell you whether it needs an inspection, and what the work involves, before anyone travels.
