I have an LG orbit and it does not heat up the food. Everything else works!! Nothing is broken or damaged. model no. LMS1240TW

It could be from the condenser coils are dirty, bad ventilation,not installed correctly,broken or dirty seals for the gaskets, food storage that is not organized.Or the internal parts are broken.Yes it could be possible that your fridge had quit working and you may need to buy a new one.

First, I'm not a LG Technician. Call your LG vendor for service.
*** the following is for information only. ***
* Move food items to another refrigerator.
* Do a complete DEFROST of the box. (unplug it.) Expect it to take 4 or more hours. You must wait till all water stops dripping out of the fridge. Keep checking the lower defrost drip tray at bottom of fridge. Dump out water from tray as needed. DO NOT you a hair drier or any other heat source! The heat will warp the plastic. Use a small fan to gently blow into the freezer section.
* DO NOT use an ice pick or sharp object to remove ice! Just let everything melt. (The problem of ice is inside the coils)
* Plug in Fridge but don't put any food in. Set dial temperature to the Mid range setting. Set to freezer venting to normal. Set the refrigerator to mid range. Let it cool down to 0 - 10 degrees and start making ice (in ice maker) If it does not cool down to at least 10 degrees F then call for service. Suspect bad thermostat, Blocked condenser coils, Bad pump, etc. Qualified service tech required to repair.
* Cooling okay? Reload food but don't stuff it in. Leave space between the walls to allow cold air to flow around foods. It will take a day or so to cool down food properly. Note: I may take longer if this fridge is near a heat source like a Hot water heater, Oven, Range, Steam radiator, etc.
* If your still icing up in 2-3 weeks. Then check if the coils are icing up. Defrost is not working. This needs to be checked by a tech. Have him perform annual maintenance.
* Check door seals. Kids leaving the door open? High humidity? * Note how everyone uses the fridge; are they putting hot food in it? Open hot steaming food adds heat and humidity to fridge. Hot food with thaw out other frozen food and build up frost.
* Final, Have a Tech check your fridge. Have them perform maintenance and replace worn items as needed.

There three parts that will cause this, the first is the magnetron "heats food" the most expensive part, followed by the high voltage capacitor and diode, they work in conjunction to generate the high voltage to cook the food.
