SpudFiles

Hey, it's been awhile since I've been at spud files.
I stop by to hopefully obtain help in bypassing the timer on this compressor, which I savaged from an old dehumidifier.

The compressor starts after roughly 3minutes, this may be a relay or something obvious like that. With these pictures below hopefully someone with a bit of electronics knowledge will see a way to simply bypass the 'timer'.

it would be easier to tell you if i had a circuit diagram but just off the top of my head it might be the capacitors charging or that IC but it's hard to tell.[/img]

Sorry, Can't do anything about the circuit diagram. Would it help if i said the time varies before the compressor turns on (2.30-3min).

I know bugger all about electronics, but from where I'm standing it looks like you can just take the red and white wires and wire them directly into the plug.

Awaiting some expert advice on how horribly wrong I am

You might be on the right track. My instinct is that the neutral (comp) is switched. Perhaps if i just use the neutral from the fan instead it may work.

Does it still have the thermostat on it, if so you have to cut it off and put your switch there to turn on/off

lose the control board and manually wire it up....

here is a basic diagram on how to wire one of these up

@JSR
heh, that's what I'd do
If the compressor a 3 pin connection then you just need one of these http://www.spudfiles.com/forums/viewtop ... tml#245328

Looks good, I have to clarify a few things though.
What is the overload protector? Is there one on the circuit board that I can remove? And same question for the relay basically i.e. Do you see one on the circuit board I can remove?

Also the voltage is 220-240v/50hz and 1.3A current, so is it good to go straight from the wall plug?

Looks like the circuit board is just a timer, nothing that looks like a power supply or anything like that. So you should be able to just omit the circuit board completely. Also omit the micro switch.

Looks to me like the brown wire from the main switch goes to the red wire of the compressor. The white wire on the compressor goes to the blue wire of the power plug.

Does the compressor label say 240V?

2 pin, from the neutral wire. Maybe it still does the same thing?

It says 220-240v ~50hz

Yep thats it, red, white comming from the relay and earth is all you need.

To make it simple, I modified your wire diagram. The de-ice is a timer to shut off the compressor to defrost it on a regular cycle. Remove the board and tie the wires together as shown. This will connect power directly to the compressor without the timer.

Thanks, Techician. That will come in handy.
