To keep your Dometic refrigerator running smoothly and efficiently, you should clean the gas burner after prolonged exposure to gas, at least once a year. Contact your local NCC Approved Workshop to book in for a fridge service where the below procedure will be performed and the Flue Cleaned out. We are available on 0845 8698940. However if you are a technical person you may wish to tackle the job yourself using our handy guide to cleaning a dometic gas burner below (The process for Thetford fridges is very similar but with slightly different design of burner / jet and different external fridge vent covers)

When using an underslung LPG tank or refillable LPG cylinders, the service interval is reduced to twice or four times a year, depending on the level of contamination.

Contamination in the gas burner becomes noticeable with poor ignition process and sometimes soot is present at the Flue exit (Dark deposits on the outside of your Motorhome / Caravan on the top external fridge vent.)

WARNING!
Before servicing your Dometic fridge burner:

  • Close the gas manifold isolation valve to the refrigerator before cleaning the gas burner.
  • Allow the burner to cool down before cleaning it.
  • Do not modify any of the gas equipment. The gas burner can be cleaned without removing the gas equipment.

1 – Remove the External fridge ventilation grill by pressing the catches shown in Picture A below up or if you have the Circular fixing then these unscrew.

2 – Remove the plastic condensation container and the screw that holds the burner cover in place.

Remove the burner cover by pressing the catch below inwards, and pulling it off gently outwards.

3 – Clean the burner pipe of using a suitable cleaning brush with soft bristles (these can be bought online as flue cleaning brushes)

4 – Blow out the burner pipe with compressed air either from an airline or from a compressed air can through the slots in the burner pipe

  • Screw the burner cover back on
  • Refit the condensation container
  • Refit the external fridge ventilation grill

fridge vent winter covers

As the joy and warm sun of Summer fade and we descend into Autumnal weather then so does the temperature drop and even more so as we hit full on Winter. If you use your Motorhome or Caravan all year around then you may have noticed that your fridge doesn’t perform as well as it used to. This phenomenon doesn’t seem logical in that during the Winter your fridge doesn’t work as well but it’s due to the chemical reactions within the back of a Absorption fridge.

If the ambient temperature outside drops below 8°c then an absorption fridge struggles with cooling as the cold air outside stops the heat exchange in the fridge from happening efficiently.

If you are going to use your vehicle all year around or indeed in cooler winter temperatures then you need a fridge vent cover, not only will it assist in keeping the back of the fridge warmer and allow it to operate but it has the added benefit of keeping your Motorhome/Caravan free of bugs.

If your fridge vents are left open during storage then the vents can allow all sorts of wildlife in such as insects, spiders etc.

Having fridge vent covers can also protect your vehicle from damp and water ingress. The covers help prevent rain and moisture from outside finding its way into your vehicle through the vents but also allows the required amount of ventilation needed, helping to prevent water build up and damp issues.

If you are going to wash the outside of your vehicle then fitting fridge vent covers also prevents water ingress.

By fitting a fridge vent cover when it is cold, it allows dangerous fumes from the combustion process such as Carbon Monoxide to escape but also stops the heat exchangr process from being too cold to function correctly.

Which Fridge Winter Vent Cover do I need ?

The type of cover you need will depend on what manufacturer model fridge you have in your Motorhome or Caravan. We supply both Dometic Winter Fridge Vents  and covers or Thetford fridge Winter Vents and covers.

eggs

Opened a bonnet on a van a few weeks ago and lo and behold a bird had set up shop with a full nest of eggs.

Have seen vermin infestations in vans before but my first full blown active nest !

Have any of you ever seen anything unusual infesting your vehicles ?

Thanks so much Mrs Lewis, they were a delight with our Tea and hope you enjoy your trip to Greece 🙂

lpg regulator expiry dates

When a habitation check is carried out both the LPG Hoses and LPG Regulator are checked and inspected for damage but also for their date of manufacture.

An LPG Regulator in a Motorhome or Caravan has a lifetime expiry set of 10 years and a Rubber LPG Hose is 5 years.

Stainless Steel hoses are designed to last 20 years, however they do have differing lifespans dependent on the use, i.e. a Filler hose will last 10 years less than the same hose employed as a Pigtail hose (Pigtail hoses are the ones that are used between the bottle and the regulator / changeover valves) This is usually labelled on the hose itself with their expiry dates.

An LPG Regulator will have either month and year of manufacture or in most instances just the year usually in 2 digit format i.e. YY whereas hoses usually have month and year i.e. MM/YY

Regulators have a whole host of different identification methods for date stamps from embossed digits in the actual body of the regulator itself or sometimes as a number on the sticker on the regulator and a suitably obtuse method of having a sundial-esque icon with two digits in the middle signifying the year of manufacturer and an arrow pointing to the month number which are around the edge of the clock face.

Due to the location of installation you may need to use some innovative methods to be able to see the dates such as using your phone camera to take photos to zoom into or the use of a inspection mirror to see behind the reverse of a regulator.

It is worth ensuring your regulator and hoses are in date not only from a safety perspective but also if the regulator fails it will prevent gas passing through into your Motorhome or Caravan and in turn ruin your holiday as you would have no heating or hot water (If yours are supplied by LPG)

See some example photos of different methods below

fridge grills overload

Had a van in for a Habitation Service and we were amazed at the number of grills on the side.

Normally a van has two grills located external to the fridge allowing access for maintenance and checks at the rear of the fridge. 

This particular van however for some unknown reason had 5 !!!
