Were is the freezer light bulb ?

One of these is a power light. It typically remains on while the freezer is in use. No light means either a blown bulb or no power. The other is associated with the thermostat. But it does NOT indicate that freezer temperature is appropriate. Flickering appears to indicate the bulbs are simply failing. The bulbs are neon, I think, and are not cheap. Some might try replacing such with LEDs. I have seen comment that the bulbs are not long lasting. www.manualslib.com has numerous danby freezer manuals but I do not know your model. Have a look.

Are you making the voltage measurement with the motor connected?

yes to both, and I believe to remove the light bulb cover you gently lift up and out to gain access to the bulb.

The light bulbs are shown in the diagram on this parts site.
Check out the location and find the type of bulb you need.

An owners manual I found online says:
Freezer

1. Pinch rear tabs on light cover and pull straight down.
2. Remove light bulb.
3. Replace bulb with appliance bulb no greater than 40 watts.
4. Insert front tabs of light cover into freezer liner and snap rear portion over light assembly until rear tabs engage.

The manual illustrates the bulb is behind a plastic grille right by the temperature control knob.

Check the condenser is clean and the fan running. Check for compressor hummimg

Hi
Most freezer lights are screw on bulbs. Unscrew the bulb unticlockwise and replace with a new one.

Is that a florescent bulb in the freezer? Or is there some kind of light bulb in the freezer? If so, change the bulb. I'm not being funny. You give no information on what make, brand and year of the freezer to give you any help.

Most likely, you never notice the light bulb in your freezer or refrigerator until it is not working. Then it is time to replace the bulb. This is especially important with freezers, which are often in areas with poorer lighting, like basements or garages. Fortunately, the task is a simple one.
Instructions

1 Unplug the freezer to prevent an accidental shock when you remove the light bulb.

2 Open the door of the freezer, look at the top inside edge of the freezer, below the door seal and back about 1 to 2 inches from the edge. You will see a small plastic or metal panel that protects the bulb from damage and shields your eyes from the direct light of the bulb when the door is opened. Reach behind the guard and remove the bulb by twisting it to the left.

3 Put your new bulb in by inserting it into the socket and twisting it to the right to screw it in. Be sure you use a freezer bulb--it is built a little tougher and is the correct wattage. You can find them at appliance or hardware stores. Plug the freezer back in to test operation of the bulb.

Have a nice day! : ))

Check the door switch to see if is working and try another light bulb or try the light bulb somewhere else to see if the light bulb is good. Check to if vent holes coming from the feezer are blocked by something in the fridge. This will make it feel like your fridge is not working.
