F03 in brief
F03 means the touch control module, the electronics under the keys, has an internal communication error: the fault is inside the module rather than between it and another part. A breaker reset is the one owner step; if the code returns, the module needs replacing.

Signs that go with the code
- Keys do not respond, or respond erratically — The module that reads them is faulting.
- The display shows the code at power-up — The module checks itself as soon as power arrives.
- The code appeared after a power event — Surges are hard on small electronics.
- NEAR MISS: a pan or spill sits on the controls — That is pressure on the panel, a different code; clear it first.
Causes, most likely first
- Touch control module failed — The most likely cause: the reading points inside the module, and an internal fault that survives a reset means the module itself.
- Passing error after a power event — Second: a one-off power disturbance that a clean restart resolves.
- Heat or moisture reaching the module — Third: steam, spills or heat from cookware near the controls stress the module and trigger errors.
- Supply problem to the cooktop — Last: a poor supply, which usually affects more than the cooktop.
The order to check, and why
- Breaker reset — The one step that separates a one-off from a failed module.
- Let the controls cool and dry — If the code followed steam or a spill, give it time before the reset.
- Note when it appears — At power-up, during cooking or after cleaning: each points somewhere different.
- Check other appliances after a power event — If others glitched too, the reset is probably the whole fix.
Owner steps, with tools and time
- Breaker reset — Switch the cooktop’s breaker off for a minute, then back on.
About 2 min
- Cool and dry — Turn the zones off, let the glass cool, and dry the control area before the reset.
Tools: microfiber clothAbout 15 min
- Watch the next cook — Cook normally and note whether, and when, the code returns.
Tools: notepad or phoneAbout 2 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.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The electronics under the glass run at high voltage and are not owner-serviceable; owner checks stay on top of the glass and at the breaker.
When this is a service call
Call when the code returns after a breaker reset, or appears at every power-up. An internal module fault is fixed by replacing the touch control module under the glass, which means lifting the cooktop with the power off.

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 F03 yet.
