The only hesitation I would have in purchasing this temp controller is the "relay contact capacity rating" It shows it rated for 10 amps at 250 volts. I am not sure that is enough for the start-up amperage for a refrigerator compressor.

I would also want to know what the rating would be for the 110 volt model.

The relay rating is good, those are actually the contact ratings. up to 10A and up to 240V, plenty for a fridge.

Worth trying.

Heating and cooling temp controller for $20? Looks good to me, let us know how it works out.

Ohhhh, very tempting!

i might have to get it since its a 2 stage for $30 shipped you can't beat that just need to see how much the fridge pulls

they also have this 1 http://cgi.ebay.com/Digital-Temperature-Controller-Thermostat-Aquarium-99-C_W0QQitemZ280460661009QQcmdZViewItemQQptZLH_Defau ltDomain_0?hash=item414cc21111#ht_4577wt_1165

which is 20amp cooling and 10 amp heating

???

These look great. I hate to buy from Hong Kong though... that's the only thing.

Please let us know how this goes. Thanks.

I bet Hong Kong has it manufactured in China like Taiwan has to save on their labor costs.
Think about it, how bad it is that even Taiwan has to use Chinese labor?
We laughted at transistor radios back in the early 60's, "hey look Made in Japan".

Hong Kong is in China.

I wasn't clear. I don't like to buy auctions from anywhere overseas. I feel the same about buying from London as I do from Hong Kong.

The "fine print" at the bottom of the listing states that a 110V model will be shipped if you live in the US.

I am not sure I am correct about this, I need a real electrician to chime in here, but I think the Amperage rating will go down with the Voltage rating. I know that would be true for wiring but I don't know if the same would apply to these relays.

I HOPE these work - I would like to get one if they do.
