Fridge doesn't appear to be cooling on 12 volt (1 Viewer)

[Grasmere9]

Afternoon! I hope you're all having a good Monday. At the weekend I took the motorhome out for a weekend of Motocross...has just had a habitation service and low and behold the fridge didn't seem to be getting cold on 12volt . I swapped to gas and it was amazing!
Any suggestions before I get back to the guy who serviced it? Thanks

The fridge is only designed to run on 12v when the engine is running. If you are parked up you need to use gas, or 240v if EHU available.

Not wishing to teach egg sucking but are you aware that it prob only runs in 12v with the engine running and producing enough power ..?

Really?! How the heck did I not know that?!

Is it wired to run on 12v with the engine off, many are not even if capable of doing so.
There are 3 ways to wire a fridge.
1, Habitation and cab battery connected and switched by relay or other control from D+ signal when engine is running or not
2, Cab battery only connected and selected by relay or other control from D+ signal when engine is running
3, Connected to habitation battery only (generally for compressor fridges only.
Then if you have a solar panel and a compatible regulator and fridge you can have it connected to the S+ output from the regulator to select your habitation battery when its fully charged.

Now I feel like a right fool

Next issue is a minor one but when I press the toilet flush I can hear it trying to rinse but only a tiny trickle coming out!
Have I missed something simple here too?

....... only a tiny trickle coming out!

That's generally age related!

 

[Russell's Dad]

Tank empty?

Ah yes this could be that your toilet has prostrate problems.

Have you got a seperate tank for the loo or does it use main tank? Whatever you have is there water in the tank?

Main tank feeds toilet...N&B Arto

Depends on your van possibly. My previous van had a separate tank for flush water. My current one doesn’t. Someone else with a similar van will know better.
Don’t feel silly for asking any questions. Unless you were specifically told about the fridge and 12v it’s easy not to know. Hope you enjoyed the mx. Where were you? We were at Northchapel, West Sussex. Good days racing, a tad dusty though which was a change from mud

Oh dear it could be latex gloves and lube time

You haven't compressed the feed pipe to the bowl when putting the toilet cassette back in?

We had a similar problem a year or two ago but it was because the residual water in the pipework had frozen!

We were at Astbury in Cheshire. It was my son's 4th ever race. He came 17/29 on day 1 and 23/31 on day 2. It's such a tough sport!

Will pull unit out and take a look!

 

[Grasmere9]

So... outside in van. I have switched the water pump on and held the flush button down for a bit. Little bits of stuff are occasionally coming out. Am thinking it must be blocked...next is how to unblock the pipe

Is it black bits coming out?
If so, it'll be mould in the pipework.
We get that if van has been laid up for a month or two.
You might want to just keep pressing the flush button and it might clear.
It normally does with ours.

Not black but brown paper thin bits that look like fish flakes
My water tank is full so will keep trying

Could still be mould by the sounds of it.

If you toilets flushes with its supply drawn from the main tank, it relies on a small solenoid valve to open so the water doesn’t flush when you have a sink tap on, it should be near the loo check it is fully opening/

I have cut an old phone cable up and am using it to push into the pipe from the bowl end! Slowly getting lots of bits out and more water!!

Ok. Will investigate that next!!

Stupid question but what will it look like? What a way to spend my Monday

 

[Clivefog]

Ours has a valve right up in the rim, it is clogged with said brown/tan stuff. Thetford suggest a new one which required the loo to be dismantled. I've got one but not the inclination to do the dismantle. We keep a squirty bottle with water/rinse mixture, which works better than the flush. Wife still wants the new valve fitted.

This sounds like a plan
Not really getting any better...

 

[BouncyBoatFolk]

The solenoid housing quite often also contains a filter/ mesh screen. It sounds as though that's blocked.

I think you're right...I think this is beyond my skills
