Fridge Vents & Water

[voyager_fun]

Hi all I have noticed behind our new MHs fridge vents is the fridge electricals (obviously) but also the rear of the wooden panelling that makes up the units.

How does one protect the inside of this 'vent tube?' from water? I'm thinking sideways rain both when camping and in storage but also from the jetwash. I can't imagine water touching inside here is a good thing.

I've heard about vent covers but surely if the fridge is on these can't be used.

Hello and welcome. I’ve never had water get it through the vents - don’t use a jet wash on them! The covers are designed for when the temperature gets below about 8C.

First I would use a jet wash and second fridge vent covers aren't for keeping water out they are to make the fridge more efficient in cold weather

I also didn't have issues with water getting in, not from the side rain nor from the auto car wash. When manually washing, I just avoid the vents, or try to aim at them from above.

In my Burstner manual it suggests you fit the fridge vents when the temperature drops to below a certain temperature but also if being stored over winter. Our MH came with just the one vent for our tall (142lt I think) Thetford fridge. Our local caravan shop wanted over £25 for what is a sheet of plastic about 3mm thick (probably costs significantly less than a pound to make in China). Instead I ordered a sheet of 3mm A4 foamboard off Fleabay, laid my existing cover on top, penciled around the shape and then cut it out. Fits and works perfectly.

I never use a Jet Wash on our Van

Personally I would never use a jet wash on a MoHo.

Neither do I. Meant to say wouldn't, too late to edit

As well as cold weather you are supposed to fit the vent covers when washing the van.
You should never use a pressure washer on a Motorhome.

the wires behind vents will get moisture or condensation road spray eventualay get small brush bit of silicone grease on the end of the exposed wires earths lives ground ect ect brush a small bit of silicone grease on spade connectors ect ,do not cover pcb with this gear theres a spray for that and that saves the pcb from corossion .i not used covers for years now as i have melted a few

Don't put the top cover on when running on gas then they won't melt.

Before I got winter covers for them I used lids from plastic storage tubs zip tied on. Works well, possibly better than winter covers.

Thanks all - lots to think about then. Looking at the vent angles it does seem difficult for rain to get in I suppose.

As a side note why is everyone so opposed to jetwashing their MH’s? Genuine question - I’d have thought you’d have for sure atleast had to do the arches and stubborn dirty areas..

Depends on the strength of the pressure washer.

High power could push through the window seals.

I use a pressure washer and when near windows and vents, set it to low which is no more than our normal water pressure and always aim away from the vents and at the centre of the windows spraying outward.
