waeco fridge

I have a waeco fridge in my boat with a danfoss compressor unit. The compressor turns on and the fan runs for a few seconds before it shuts off. I get two flashes on the LED which I believe means the fan is using over one amp of current. I replaced the original 0.4 amp fan with a 0.25 amp fan and got the same results. All the wiring is good, the connectors are good, and the voltage is high. Any thoughts?

Re: waeco fridge

Make very sure you have good voltage, low volts = higher amps. Double check all your wiring! and the connections! And be very sure you have a good ground. Try it without the fan wired in. if it still cuts out it may be the module.. How old is it? Do you get any cooling effect at all? Oh, make very sure the fan is connected to the correct terminals it's easy to get them wrong.

Re: waeco fridge

The voltage is good. This happens when the boat is plugged in to AC power too. The wiring is all good as are the connections. The ground is good. Without the fan it runs well, cools, and the coils stay quite cool. The cooling effect is good. It is four years old. The positive lead for the fan is connected to the battery power lead and the negative for the fan is connected to the F terminal directly below it. The fact it works without the fan is strange as it is a 0.25 amp fan. I tried to get a current reading and found my 10 amp fuse in the meter is blown. The 40 mA scale shows overload so it is over 40 mA and below the 1.0 A that the fuse blows at. I will take my meter for a new fuse to the place that sold me the fan and then we can see what it draws. I'll check the old 40 mA fan too. Thanks for your help.

Re: waeco fridge

They actually can work without the fan unless it's very warm or hot in the compressor's environment. Here's the PDF link. I does sound like the fan is the culprit. IF the fan's + connection is on the battery + that may affect it since there's a + just for the fan.
(if I have the right schematic)

Fan (optional, Fig. 1)
A fan (5) can be connected between the terminals
+ and F. Connect the plus to + and the minus to
F. Since the output voltage between the terminals
+ and F is always regulated to 12V,
a 12V fan must be used for both 12V and 24V
power supply systems.
The fan output can supply a continous current
of 0.5Aavg. A higher current draw is allowed for 2
seconds during start.

Re: waeco fridge

The schematic does not correspond to my unit. I can have a look for the connections tomorrow but there is no positive pin for the fan on my unit. Rather the positive for the fan hooks directly to the battery voltage terminal above it. It will be interesting to see what current the fan draws.

Re: waeco fridge

Cam the Danfoss site has a whole list of files. I didn't have your particular model number. they are all somewhat similar in wiring however. The modules are hyper sensitive and seem to get more so with age. Not quite "solid state"

Re: waeco fridge

Thanks for the advice. I will check the current draw of the fans and buy another if necessary. I'll also check the danfoss files.
