FrigoBoat refrigeration

We have a 2004 IP445 with a Frigoboat fridge/freezer and Carel Electronic controls. Recently, the fridge section has been freezing and does not seem to respond to our attempts to reprogram the temperature. (The temperature setting on the Carel control is actually 40F but the compartment actual temp is about 20F)

Any ideas how to reset the temperature?

Also, I believe this is a keel cooler design. Has anyone used the Frigoboat optional air cooled accessory? It would seem that adding the air cooled option would be very useful when we haul out.

I have the same setup, but in a 2007 440. Awhile ago, after being away from the boat for 2 weeks, I came back and the fridge was at like 12 degrees and everything was frozen solid. Beer bottles exploded and everything.

I cycled the power on the controls and it came back to life, just like normal. Like it had a glitch in the system or something. Has been running fine ever since. If you haven't tried yet, maybe it just needs a time out for awhile?

Good luck,

Hi folks

Just wanted to follow up on this. We ended up doing a factory reset on the system and it's now working great. We're holding temp to with one degree on both fridge and freezer. Just cycling power didn't have any effect but the reset worked fine.

Thought you might want to know.....

Blair:
Thank you for letting us all know the inside scoop on how you fixed this and the process of a good factory reset.
Great job and thanks again.

As a pilot I have learned from the mechanics that there are resets and then there are RESETs. First turn off the equipment circuit breaker. Leave it off for TWO minutes! I don't know why two minutes is key but I have seen it make a difference on many occassions. If that fails remove all power (AC and DC) from ship (airplane/boat) and then repower the ship and then the effected equipment. Depowering a jet half way through preflight is not done lightly but it is occasionally the only thing that can be regain the effected equipment. This especially true with electronics.

spinaker75is correct in respect that there are different forms of "RESETs".
Most electronics have two forms of memory. Volatile and Non-volatile. Volatile memory can be erased (reset) by a power dump. However, most error's and error codes are held in Non-volatile memory. Which as the name implies, stays latched after a power dump and/or power failure.
To erase these, a memory erase must be done. Which is what you are doing when you do the Fridg-O-Boat's reset.

In Avionics, this is referred to as a B.I.T.E. (Built In Test Equipment). If the fault is a phantom error, the unit will reset and then operate normally. But if there is a hard fault, it will fail the B.I.T.E., throw a code, and continue to mess up until the fault is corrected.

Kinda like your "Check Engine Light" on your car. You might be able to reset it with a OBD II tester, but any hard faults will come back. Causing the light to come back on.

Soooooo...
A power dump will sometimes get rid of nuisance errors. But any latched errors will need to be reset using the manufacturers procedures.
If it comes back, then you have a hard fault.
