Hi @atuhutrire alison
OK I finally located your model (sorry about doubting the number)
It appears that it is a model for Africa.
There don't seem to be any parts suppliers or any other information e.g. service manuals that I can find online so you may have to contact Samsung, in your location and ask about where to obtain parts and their availability.
As I said, one step at a time.
If the heater solves the problem all well and good. You can verify the heater before installation by testing it to see what its' resistance is. If it is what I said then you know at least that the original is faulty.
With most refrigerators, they go into auto defrost mode once every 8-11 hours. During this time the compressor and evap fan are turned off and the temp in the freezer is allowed to rise to 0 deg. C to melt any ice which drains away to the evap pan under the refrigerator cabinet . The melting process is sped up by turning on the defrost heater.
When the temp reaches 0 deg. C the defrost thermostat operates to end the cycle by signalling the control board to turn off the heater and to restart the compressor and evap fan.
This whole process takes about 20-25 minutes and is repeated every 8-11 hours.
The timer is part of the control board

Hi,
What is the full model number of the freezer?
Did you measure the heater element and the thermostat, individually and in isolation i.e. disconnected from the wire harness and the meter probes connected directly to the component's connection terminals?
Normally for a good heater element the resistance measurement is 20-50 Ohms. Don't know about the thermostat.
Depending on the specifications of your meter a resistance measurement of 433 Ohms may be above the limit where the continuity test works as continuity is usually just a quick test to prove that the wire/switch etc is OK and it is normally only a very low resistance <1 Ohm.
Also what component measured 433 Ohms? That's definitely too high for a heater element.

Thanks for getting back to me jayeff
I appreciate, actually what I was working on was a fridge.
So the thermostat and the heaters were connected together and had two brown wire connected on either end, so I disconnected them from where they receive power and I set my multimeter to a ×1(where a continuity beep is always heard) so I measured (as they were still together) and that reading of 433 is wat I saw
So I got confused and I dnt know what is which
But you have said that that reading is really to high so I guess it's a faulty heater but then what about the thermostat.
Plus I failed to locate the timer of the fridge

Hi,
Your comment was deleted by the iRobot because it contained long number strings which it think are spam phone numbers.
I saw your deleted comment but the model number you posted i.e. Samsung RT 31FAREDSA, gets no results when searching online for that number.
Please verify that the model number is correct?
Also do not put personal contact details online as this can expose you to spam or worse.
Just commenting back here will get attention especially if you add @jayeff in the comment ;-)

Hi @atuhutrire alison
If you measured the heater by itself and got that reading it is too high.
If the thermostat is a thermistor type then its' resistance will vary with temperature.
It might be one step at a time.
See my comment above about the model number. Usually there aren't that many letters in a model number
