On current Marvel undercounter freezers, HH appears in the display when the compartment temperature stays above the control setting for an extended amount of time. Marvel does not give an owner fix beyond contacting service, but the usual causes are an open or poorly sealing door, a blocked grille or a cooling problem. Marvel freezer display What to do when HH shows on the freezer ### Kind of code Temperature and alarms The freezer measured a cabinet warmer than it should be and said so, sometimes with the highest temperature it reached while nobody was looking. The cause can be as simple as a door left ajar or a long power outage, or as serious as a compressor that stopped. Keep the door or the lid shut and check whether the food is still hard before anything else; the alarm is a warning about the food, not a diagnosis. ### Usually leads to Freezer thermostat and temperature control repair Repairing the dial thermostat or the sensor and control that decide when a freezer cools, so it stops running without end or quitting too early. ### Shows up as Freezer Error Code A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running. ### Make Marvel Marvel freezers repaired where they are installed, with the airflow and the seal checked before any part is replaced. ### Source Marvel User Guide, MLFZ224 24-inch built-in high-capacity freezer (marvelrefrigeration.com PDF) MLFZ224 and MOFZ224 (outdoor) with the touch control; the Professional MPFZ424 guide does not list HH. Older ML24FA units flash a TEMP indicator instead. ## Before you book, in this order. Each step comes from Marvel's own guidance for HH on its freezers. Follow it to the end: the last card says whether this is a visit. 01 Feel the food: if packages are softening, move them to another freezer or a cooler with ice. 02 Close the door firmly, clear anything in front of the bottom grille and check that the unit is not in direct sun. 03 If HH stays after a few hours with the door shut, book a visit. ### Still there? It usually turns into [freezer thermostat and temperature control repair](https://freezerrepair.center/services/thermostat-and-temperature-control-repair/).

Feel the food: if packages are softening, move them to another freezer or a cooler with ice. If it comes back, it needs a visit. ### Why did HH come up after I loaded groceries into my Marvel freezer? A large load of room-temperature food can keep the compartment above the setting for hours. If HH clears once the load has frozen, nothing is wrong; if it stays, book a visit. ### Does a hot patio set off HH on a Marvel outdoor freezer? It can, since high ambient heat makes the freezer work harder. Check that the grille is clear and the unit is out of direct sun before assuming a failure. ### Is food safe after a Marvel HH notice? Check it by hand. Items still frozen hard can stay; anything that has thawed should be cooked or used rather than refrozen. --- **[Read on the site: Marvel HH: the freezer has stayed above its setting for too long](https://freezerrepair.center/error-codes/marvel-hh/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
