funlovincriminal 120 Posted October 25, 2022 Share Posted October 25, 2022 The Engine driven compressor/plate/brine freezer on our 1020 is hell bent on sending me to the looney bin, and possibly divorce court. Its a standard factory fitted interior with a top loading stainless lined freezer in chart table surrounded on all 4 sides by the brine tank and front opening fridge utilizing the back of 1 freezer wall. Load boat up for Bay of Islands trip, go down and fire it up, Load freezer, flick compressor on and within 5 mins there's a healthy frozen line moving it's way up the walls of the freezer. Running it for 1 hour has the whole thing chilled down super well and off you go enjoying cold beers from the fridge safe in the knowledge your steaks will still be frozen days later. Day 2, fire boat up to motor out of Tut's and head up the coast. Flick the compressor on for a cool down 'top up'. turn off after an hour and notice that it hasn't really appeared to Ice up like the day before. Doesn't concern you, maybe some kind of thermostat thing where system is telling you "hey don't worry - still all frozen in here" Day 3, motor out of Paradise Bay towards Russel with fridge on. Hmmmm - this thing ain't working. Compressor clutch clicks in, engine revs drop a bit but nothing flowing through sight glass and return line not freezing up. Start to panic, food at the top has defrosted. Phone and ask wife to bring the 12v Dometic unit up from home when she meets you. Make plans to empty freezer and divide perishables between friends boats freezers. Revise meal plan to eat top layer of food first. That afternoon, after picking family up from wharf you try it again and boom! - Elvis is back in the building. Freezing faster than Kim dot Coms assets. Must have been a glitch in the matrix. Yeehah, cancel plans to shorten family holiday and move on with your life.... except.... Day 4, Elvis is Dead on the Toilet. Resume panic stage... then repeat above steps for remaining 10 days of your trip. That was our new years trip. Since then we have done a couple of overnight trips with pretty much the same result. Fantastic for a day trip, but no good for multiple days. This Labour weekend was the same - Froze down Friday, didn't work Saturday or Sunday, fired back into life Monday on the way home. Anyone with experience of this phenom? Boats been back in the water for a year following a decent refit. Had never used it before then, the only modification to fridge system I undertook was remaking engine mount/compressor bracket to relocate compressor to the space under quarter berth instead of hanging through wall of engine compartment and burning a hole in the bedding. Hoses were never disconnected in this process but the compressor orientation was altered perhaps 90 degrees - are they fussy about that? It's been suggested it could be a jammed TXV, could this be the case or is it simply adjusted to only work above a temperature that's not low enough for the freezers purpose? Frustrating that when it works it's amazing - but only works when it wants to. Fire away! 3 Quote Link to post Share on other sites
