It also has an automatic setting that finds its energy source without you needing to change it manually.  **Instructions:** **Please note: ** -  Remain as level as possible when running the fridge. If you need to park on a steep slope, you may need to turn it off (The fridge decreases in temperature by only about 1 degree Celsius within 24 hours if turned off)  - Get your fridge serviced annually, as the gas jets can block up over time. This can be done as part of your annual service check. - Run your fridge regularly even while your motorhome is in storage.  - When operating your fridge on the automatic setting, there can be a 10-15 minute delay switching between settings.  - When the fridge is not in use, turn it off and use the ajar function to avoid mould and odour build-up.  - Avoid spraying water in the fridge vents when washing the outside of your motorhome.  #### Troubleshooting [Click here to learn what to do if your fridge isn't operating on gas](https://knowledge.traillite.co.nz/en/knowledge/what-do-i-do-if-my-dometic-fridge-isnt-working-on-gas?hsLang=en)   - [General Help and Information](https://knowledge.traillite.co.nz/en/knowledge/general-help-and-information?hsLang=en) - [TrailLite Information and Guides](https://knowledge.traillite.co.nz/en/knowledge/traillite-information-and-guides?hsLang=en) - [Benimar Information and Guides](https://knowledge.traillite.co.nz/en/knowledge/benimar-information-and-guides?hsLang=en) - [Fusion Information and Guides](https://knowledge.traillite.co.nz/en/knowledge/fusion-information-and-guides?hsLang=en) - [Mobilvetta Information and Guides](https://knowledge.traillite.co.nz/en/knowledge/mobilvetta-information-and-guides?hsLang=en#main-content) - [KP model](https://knowledge.traillite.co.nz/en/knowledge/mobilvetta-information-and-guides?hsLang=en#kp-model) - [Both models](https://knowledge.traillite.co.nz/en/knowledge/mobilvetta-information-and-guides?hsLang=en#both-models) [![Chill listening crop-3](https://knowledge.traillite.co.nz/hs-fs/hubfs/TrailLite%20Group_Primary_Gold_RGB-2.png?width=200&height=49&name=TrailLite%20Group_Primary_Gold_RGB-2.png "Chill listening crop-3")](http://traillite.co.nz) Contact our friendly service teams for more information or assistance.
