Re: New Thread on A54 fridge pumps (ATTN: OLIVER Vela Nautica)

My response in red: Jamie, Your 12V pump is looking for about 4A supply at 12V according to its specs. The system is designed to operate with a pump supply current of 1- 1.2A at 12V. I suspect you have damaged your 51385 module. I don't think so. It is the Danfoss Compressor controller that has the limit. If you have an LED alarm you will get 2 Blinks with "Excessive load on fan terminals, above 0.7amps." Remember the voltage for the 51385 comes from the Danfoss Compressor controller. See schematic below with 1 Danfoss circled and also snips from the manual :    Did you ever connect a different 12V pump from the specified pump by Frigidaire ? Maybe your 51385 is also fried. Above Arno, I agree with your description. Jamie, I suggest to buy the correct pump, and with a 'working' 51385 (operating at 12V) everything should be fine. Agree Using the correct 24V pump, the pump is safe under fault conditions, so you won't damage the pump if the voltage regulation on the 51385 fails. The 24V pump operates on a lighter duty than a 12V pump operating at full tilt. This extends its life and makes it quieter. Just need to be careful with specs about the pumps. Veco rebadge the Flojet 24V pump as a '12V pump' for continuous duty at half the flow rate. This can be very confusing when discussing the pump, or trying to replace it with a different one. Agree
