Hi, I'm Mat from eSpares.
In this video, I'll show you how to use a multimeter
to test the fridge freezer temperature sensor
on your fridge freezer.
If your fridge is not cold enough
or it's feeling very cold and is freezing your food.
It may be that the temperature sensor is faulty and it needs to be replaced.
The best way to test this is with a multimeter.
Now we're going to be using on this video the fridge compartment
but the process for a temperature sensor on the freezer compartment is very similar.
A multimeter is a test tool
designed to measure two or more electrical values for Voltage, Amps or Ohms.
When testing parts in an appliance
you can use the multimeter to check for these measurements.
If the reading is above or below the required amount
or there is no reading at all
it means the part is faulty and will need to be replaced.
Before using your multimeter make sure your appliance is switched off
and fully disconnected from the mains.
For this repair, you'll need a multimeter
a Phillips head screwdriver and a flat head screwdriver
and you can find a link to these
in the description below if you don't already have them.
The first thing you need to do is to remove the contents of your fridge
as well as any shelves or drawers.
Next, we need to remove the evaporator cover.
Before we do that just check that there's no ice
in the screw holes or in the vent
because if there is, it could mean there's ice behind the cover
and you will not be able to remove the cover without damaging it.
So leave it to defrost for around 48 hours and try again.
It's a good idea to place a towel at the base of the fridge
to soak up any water during this process.
If you don't see any ice you can go ahead and remove the cover.
First, release the two clips from the top
by pricing them away with a flat head screwdriver.
Then remove the two screws
at the top of the cover and the two at the bottom
and also the two screws that hold the tank in place
because you need to remove that as well.
You can now pull the evaporator fan cover towards you.
There are electrical connections
holding it in place at the top here so just disconnect those
and then you can lift the evaporator fan cover out of the way.
On the right-hand side when facing the fridge
you'll see a block of three plugs
and disconnect the top plug
as this is the one that's connected to the temperature sensor.
Then unclip the temperature sensor from the gas pipe.
To set up your multimeter
place the black probe into the black socket at the bottom of the multimeter
and the red probe into the red volts socket here
and set the resistance on the multimeter to 20,000 Kilo Ohms.
To test your temperature sensor
attach the two probes of the multimeter
onto the electrical connections and you should have a reading.
Now if you put the temperature sensor
into a mug of very cold water or ice.
The reading should continue to rise
which means your temperature sensor is still working.
If it doesn't rise
this means your temperature sensor is faulty and it needs to be replaced.
Once you discover that your temperature sensor is faulty
you're going to need to replace it.
To do that you need the exact model number of your appliance
and if you see our video here
it details exactly where to find
the appliance model number for your fridge freezer.
Once you have the correct model number
you can then purchase
a brand new temperature sensor from the eSpares website
and there's a link to where to find that in the description below.
Fit the temperature sensor to the gas pipe
I'm just connecting it via the plastic fitting
and then fit the electrical connection into the plug.
You can then place the evaporator cover into position
refit the electrical connections
then refit the screws two at the top, two at the bottom
and also the two that hold the tank in place.
You can then fit the covers at the top
making sure they click into place.
Then replace any drawers and shelves and of course food and drink.
So there we have it.
How to test a temperature sensor on a fridge freezer
using a multimeter.
Now that your fridge freezer is up and running again
it's a good idea to make sure that it's running as safely as possible.
