--- title: "ZLINE FCIND induction cooktop showing E4" description: "What E4 means on ZLINE FCIND induction cooktops, what to check before booking, and when it is not a failure at all." url: "https://cooktoprepair.center/error-codes/zline-fcind-e4/" --- # ZLINE FCIND induction cooktop showing E4 E4 on the FCIND means a zone has detected abnormally low supply voltage. ## What E4 actually means. E4 on the FCIND means a zone has detected abnormally low supply voltage. Low voltage leaves the induction circuit unable to run properly, so the cooktop stops the zone and ZLINE asks you to check the power supply. ZLINE cooktop display What to do when E4 shows on the cooktop ### Kind of code Induction power and coils An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then. ### Usually leads to Induction board and coil repair Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls. ### Shows up as Cooktop Element Not Heating A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil. ### Make ZLINE A US company that sells gas cooktops and rangetops, often bought online and installed by the owner's own contractor. ### Source ZLINE FCIND induction cooktop user manual ZLINE FCIND induction cooktops with anti-scratch glass (FCIND-24, FCIND-30, FCIND-36), July 2026 user manual. The older RCIND cooktop and the SINRT induction rangetop use different code lists. ## Before you book, in this order. Each step comes from ZLINE's own guidance for E4 on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Check the breaker for the cooktop and whether anything else in the home is short of power. 02 Do not open the junction box or touch the supply wiring; a low-voltage problem in the home is work for an electrician with the power off. 03 If the supply looks normal and E4 remains, book a visit. ### Still there? It usually turns into [induction board and coil repair](https://cooktoprepair.center/services/induction-board-and-coil-repair/). Book with the code and the model number. ### What not to do On the older RCIND, E4 is a sensor code, not a voltage code. It is also not an overheating code, so waiting for the glass to cool will not clear it. ## What you may notice with it. The cooktop problems E4 tends to arrive with. Answer these at the cooktop before anyone is booked.

Check the breaker for the cooktop and whether anything else in the home is short of power. If it comes back, it needs a visit. ### Why does E4 appear on my ZLINE cooktop when the dryer is running? A heavy load on the same supply can pull the voltage down. If E4 shows only then, have an electrician look at the circuit. ### Does E4 on a ZLINE cooktop mean the board is bad? Not necessarily; the code reports low incoming voltage. The supply is checked first, then the cooktop. ### Why does E4 stop only one zone on my ZLINE FCIND cooktop? ZLINE describes E4 as a zone detecting abnormally low supply voltage, so the code appears with the zone that measured it. If other zones or other appliances also struggle, the supply is the likely cause. --- **[Read on the site: ZLINE FCIND induction cooktop showing E4](https://cooktoprepair.center/error-codes/zline-fcind-e4/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
