What the display is telling you
Er 47 means the touch control module, the part under the keys, and the control board that runs the cooking zones have stopped talking to each other. Until a breaker reset brings the conversation back, the cooktop cannot be operated reliably; if the code returns, it needs a technician.
Error codes
Reference| Code | Meaning |
|---|---|
| Er 47 | There is a communication error between the touch control module and the control board. |
What you notice alongside Er 47
- Keys light but nothing heats — The touch module works; its commands do not arrive.
- Zones switch off unexpectedly — The control board stops heating when it loses contact.
- The display freezes or shows the code at power-up — The modules check each other as soon as power arrives.
- NEAR MISS: the controls are completely dark — No power to the cooktop at all; check the breaker first.
What triggers Er 47, ranked
- Loose or damaged connector between the two modules — The most common cause: the cable between touch module and control board loosens with heat cycles, or after the cooktop has been lifted for any reason.
- Touch control module fault — Second: the module under the keys fails and stops answering.
- Control board fault — Third: the board that runs the zones fails to respond.
- Passing glitch after a power event — Least likely to last: a surge confuses both modules and a reset clears it.
Diagnostic order
- Breaker reset — Switch off for a minute; a conversation that resumes was a glitch.
- Dry the controls if anything was spilled — Liquid over the touch area interferes with the module.
- Note what lights up — Keys and display alive point at the link or the control board; nothing alive points at power.
- Technician checks the connector — It sits under the glass, reached by lifting the cooktop with the power off.
Reset and owner-safe checks
- Breaker reset — Switch the cooktop’s breaker off for a minute, then back on.
About 2 min
- Dry the panel — Wipe the touch area dry and leave the cooktop off for an hour if liquid got near the controls.
Tools: microfiber clothAbout 10 min
- Record what responds — Note whether the display and key lights come on and whether any zone heats.
Tools: notepad or phoneAbout 3 min
- STOP here if the next check needs a panel off — Anything behind a panel is a power-off technician job, and the tests that follow it are made on live circuits.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Keep water away from the controls while the cooktop is powered, and never lift the glass top to look underneath.
When a reset is not enough
Call when the code returns after a breaker reset or keeps appearing during cooking. Reseating or replacing the connector and testing each module means lifting the cooktop from the counter with the power off, which is technician work.

Which models this reading covers
Generalized information for Amana electric and induction cooktops with touch controls. It is not a reading for Amana gas cooktops, Amana ranges, whose surface codes are listed with the oven codes, or sister brands on the same platform, whose lists can read differently. The details that change inside the line, such as wiring colours, part numbers and connector locations, belong on model pages, and none is published for Er 47 yet.
