What is the orange light for at the top of my freezer

Could you please recheck for the model number. R134A is a reference to the coolant used in the freezer mechanism.
Orange is often a reference to the 'Fast Freeze' function being turned On. Green is showing the freezer unit is at the correct temperature. Red is warning the freezer is Too warm. Some freezers are fitted with an 'Economy' function where the freezer can be run at a lower power level when not used regularly such as when on holiday.

If that orange light is on the front of the freezer, on the top or bottom, it is very likely a light telling you the freezer is not cold enough inside, and the food is in danger of spoiling.
It may also be a "on" light.
If you will find a freezer thermometer and put it inside, you can tell whether it is an "on" light or a warning light.
Usually freezers run temperatures of about 10 degrees Fahrenheit or lower if they are working correctly.
God bless your efforts.

if you turn the freezer off for some time then on again the red light has to come on as an indicator for high temperature it goes off by itself when the freezer attains the required temperature according to the thermostat settings ,that is the lower the settings the faster the red light goes off. the orange light indicates super cooling and the green light indicates power supply.if you turn the two lights off and the freezer still works without the green light on that means that the bulb for the green light is faulty and you don,t need to worry

Are you sure it is a standby light? Usually the orange light is showing you it is in fast freeze. Try switching the orange button off and monitor the temperature. The freezer should cycle on and off, not run continuously.

no. the orange light is the temperature light and the green light is the mains light.

try a total defrost,to clear any internal ice(every 12 months)then switch on and if you have a rapid freeze button leave on for 24 hours to get back to normal operating temp.if you have hard ice around the door seals then you have an air leak which you must sort out(try using a hot cloth to warm seals back into shape.....seals should fit all round, all the time.

I used to sell freezers.the green light tells you the mains is on and the freezer should work.The red light is to inform you the freezer is not low enough temperature,and the orange light is a fast freeze light to over ride the thermostat for use when introducing fresh food.It should not be used for prolonged periods as it may burn out the compressor although in your case you already have a problem and should seek advice or buy another freezer.If you get a cheap freezer thermometer it should confirm what I am saying.

The orange button is the "turbo boost" - for reduzing the temperature the fast way. Mostly used when first time use or you put in a lot of unfrozen things at once. When reaching optimal temperture it goes off automatically. The red one is the alert button. Not sure about the green one. Under normal conditions none of the lights is on.

Try advancing the defrost timer manually.
