The knob on a Garland induction unit turns a potentiometer that tells the generator how much power to send. When that part or the power switch reads wrong, the unit switches off and shows E05, or five short flashes after each long one. Garland's only action for it is a service call. Garland commercial appliance display · also shown as 5 short flashes after each long flash What to do when E05 shows on the commercial appliance ### Kind of code Controls and power The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Garland Garland equipment on a cooking line is usually looked at after close, when every burner is cold and the grates can come up without rushing a cook. ### Source Garland Induction Counter-Top Series dual base-line models GI-SH/DU/BA installation, operation and maintenance manual, part number 4532290 Rev 3 Garland counter-top induction cook-tops, woks and griddles (GI-SH/DU/BA, GI-BH/BA, GI-SH/BA, GI-SH/GR).

Each step comes from Garland's own guidance for E05 on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Turn the knob back to off and switch the unit off at its power switch. 02 Wipe spills away from the knob so no liquid runs into it. 03 Switch back on once to see if E05 returns. 04 Book a visit if it does, since the switch or potentiometer needs replacement. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do E05 is not a cookware or overheating code, so changing the pan or letting the unit cool will not clear it.

Turn the knob back to off and switch the unit off at its power switch. If it comes back, it needs a visit. ### Can spilled liquid cause E05 on a Garland? It can. Liquid that runs down a knob shaft can reach the potentiometer. Keep the knob area wiped dry. ### Is E05 on a Garland a quick repair? It usually means replacing the potentiometer or switch, which is a routine part change for a technician. ### Can I use the Garland with E05 if it comes back on? If the unit restarts and responds normally to the knob, you can finish the service carefully, but book the repair. --- **[Read on the site: Garland E05: the power knob or its sensor has a problem](https://commercialappliancerepair.center/error-codes/garland-e05/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
