Fridge Protection

[Redge]

Hi

i would like to build a circuit to protect my fridge from running to soon after being swirched of.

So there would be a 240 V AC IN (from grid) and AC OUT (to fridge) and when the AC IN is switched off, there must be no AC OUT until about 10 minutes after it was switched off, even if the AC IN

is switched on immidiately after being switched off.The fridge has draws start up power of about 900watt and running at about 140watt.

Could you help with this?

Thank you very much

There are devices similar to what you want on the market. This one has 5 minute delay. Perhaps if you poke around on ebay or amazon you could find a 10 minute one.

Else if you want to roll your own we could look at how to do.

What code book? And why do you care? Unplug the refrigerator and plug it into one of these.

Check out Fridge repair Victoria for more information on getting your fridge to run properly.

Dear, Redge

I'd check on Hackster.io to see if someone already made this invention or something similar you could work off of. But I can see why it would be a good idea if you need to turn off the fridges and want them to cool gradually. All the best.

You could use a time delay relay. This relay would be connected in series with the power supply to the fridge, and would delay the power to the fridge for a specified period of time after the power supply to the relay is switched off.

1. Begin by selecting a time delay relay that can handle the voltage and current of your fridge. For a 240V AC circuit, you could use a relay rated for at least 10A.

2. Connect the 240V AC IN to the input terminals of the time delay relay.

3. Connect the AC OUT of the time delay relay to the fridge.

4. Set the time delay on the relay to approximately 10 minutes (or whatever time delay you prefer). The exact process for setting the time delay will depend on the specific relay you use, but typically involves adjusting a potentiometer or dip switch.

5. Test the circuit to ensure that the fridge is not powered until the delay period has elapsed. If necessary, adjust the time delay on the relay until it meets your requirements.

Try it, hope it helps
