Engel fridge failure

Reads like a thermostat issue. If proper fix cost is marginal or throwaway, cheap fix might be to install an external thermostat? I have a STC 1000 ($10 on ebay) on a beer fridge when the fridge thermostat went bung. New internal mounted thermostat was more dollars than the fridge was worth. I also have a 12 Volt version on the way in the mail so I can set an Engel to 18 Degrees C for home brewing. The 12 Volt version was under $4 online. STC 1000 has LED readout, 12 Volt jobbie has you set DIP switches according to instructions.

These external thermostats turn power on and off to the fridge by breaking or making the power line so you would have to wire direct to the compressor.

My 40lt Engel started to cycle continuously, found it to be the 10 amp blade fuse where the 12 and 240 volt leads plug in, the thing is the fuse wasn't blown, just a buildup of corrosion was enough for it to start playing up, if you have never changed that fuse, it may be worth looking at.

Ok well thats one thing out of way, looks like it could be a trip to the engel man Barry.

They are very good. Workshop is a tad messy but they are good.

Thanks all for you help.
My diagnosis is that the sensing thermistor is the culprit - power supply OK, fuse OK, compressor OK, fan OK. So I've tracked one down and ordered it ($25 plus p&h $12). It looks pretty simple to install as it comes complete with plug for the main circuit box - just have to thread it through.
I'll report back with the results in a few days.

Well, it wasn't the thermistor, so in it goes for a repair quote - probably the refrigerant leaking so a new cooling element?

Over the past 37 years of owning Engel fridges, the only culprit I've come across when one plays-up is the damned cord/s and or plug/s.

Before you attempt expensive repairs, I suggest you rule out the cable......see if you can get hold of another 240 volt cable and see if it works using that.

Also, have you tried using the 12 volt side?

Good luck,
