fridges and power

I don't know about "more efficiently" but there is a gadget available that purports to reduce current draw by restricting the number of cycles per hour that a fridge normally performs.

In your case, if the fan is faulty, as opposed to the compressor, even reducing the cycle time may not fix the problem.

I don't have reference to the "black box" that reduces the cycle time, but if you search the forum, you may find reference to it.

Depends how hot you want your beer.

If its set to say 1deg ( ideal beer temp by the way ) then you can't make it more efficient unless the temp goes up..

Whats the current draw when its going ??

Brenton,
You can get the unit to cycle less by increasing the differential on the themostat if it has thermo that is capillary type.
It means less starts but the box get to a higher inside temp before starting the compressor again thus it needs to run a bit longer to remove the heat that has accumulated inside.
Might help a bit but you need to make small changes, pretty sentsive adjustment screw.

My simple understanding is that they all have a thermostat in them.

At a given temp it it turns the fridge on and then turns it off when the temp drops to the set level.

The process then goes on and on as often as is required.

Perhaps I am missing something and technology has passed me by, it wouldn't be the first time.

Brenton,

Here's a reference to the "black box" I was refering to.

I'm not promoting it and haven't tried it, I just recall it being discussed some time back.

One of 2 things is what i am thinking

some manufacturers lie thru their teeth when it comes to specifications of product....or cheat (lower/raise to suit themselves) the standard test parameters, which give erroneous assumptions

Or , could it be that you have interpreted the manufacturers test results wrongly and it uses more than you think it was going to

Brenton,
the duty cycle on 12 volt fridges, when stated in 'Degrees', should remain under +7° as is recommended by health standards assn.

How often the fridge 'cycles' is relevant to it's insulation, if it's crappy and inefficient insulation the fridge will cycle more often, if it's efficient it won't cycle as often.

If you set the fridge cabinet temperature too low it will force the fridge to cycle more often than when it's set at a slightly higher temperature.
If the fridge is still under warranty have it checked by the supplier or their agent as the 'fan' _Affordable_Storage_Drawers.aspx next to nothing when compared to the compressor.

Hi
How much your fridge runs depends on:
1 the thermo setting the lower[colder] its set the more the frig has to run
2 how often you open the fridge & for how long . the more often the longer it will run
3 the temp of what you put in , needs to run to cool it downo
4 the efficiency of fridge & insulation & the temp of the fridge location, place it in as cool a location as you can find ,shield it from heat
5 Chest type do not spill could air like upright do
Fridge cycling means little IT CAN RUN FOR LONG TIME THEN OFF FOR LONG TIME or IT CAN RUN FOR A SHORT TIME & THEN OFF FOR A SHORT TIME & STILL USE SAME AMP HRS PER DAY.
The recommended temp for food storage is max 4degrees
