HIGHVOLT is the opposite of LOWPOWER: the Vario freezer column measures more voltage than it is allowed to run on. Gaggenau says the message clears when the voltage returns to normal, and to inform the energy supplier if it lasts. Gaggenau freezer display What to do when HIGHVOLT shows on the freezer ### Kind of code Power and voltage The freezer saw its supply voltage drop, spike or vanish, and many models log that as a code after an outage or when the power returns. The outlet, the circuit, a GFCI in a garage or basement and an extension cord are checked before anything inside the freezer. If there is a burning smell or the breaker keeps tripping, switch the breaker off from a dry panel and leave it off until the visit. ### Usually leads to Freezer diagnostic visit A visit that starts with the food and the room the freezer stands in, then works through the seal, the airflow, the defrost and the compressor until one part is named. ### Shows up as Freezer Won't Turn On A freezer not turning on gives no light, no display, no hum and no fan, as if it were unplugged, even though the cord is in the wall. ### Make Gaggenau Gaggenau freezers repaired in the home, starting with the temperature they hold and the alarm they give. ### Source Gaggenau Instruction for Use, freezer RF 411, RF 413, RF 461, RF 463, RF 471 Gaggenau Vario RF 411, RF 413, RF 461, RF 463 and RF 471 freezer columns (instruction 9000909130).

Note when HIGHVOLT appears and whether it followed a storm, a utility repair or a generator switch-over. If it comes back, it needs a visit. ### What can cause HIGHVOLT on a Gaggenau freezer column? Gaggenau only says the supply is above its limit. Utility problems and loose neutral wiring are among the things an electrician will check. ### Can HIGHVOLT damage my Gaggenau column? The message is the column protecting itself and warning you. If it lasts, act quickly on the supply, and book a visit if the column behaves oddly afterward. ### Why did HIGHVOLT appear after running my home on a generator? Portable generators can deliver unsteady voltage. The message should clear once the home is back on utility power. --- **[Read on the site: Gaggenau HIGHVOLT on a freezer column: supply voltage too high](https://freezerrepair.center/error-codes/gaggenau-highvolt/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
