How to Replace an RV Air Conditioner Gasket?

If you notice any of the following, it’s time to replace your RV air conditioner gasket:

  • Your air conditioner is leaking water.
  • Your air conditioner isn’t cooling as well as it used to.
  • You hear strange noises coming from your air conditioner.

Replacing an RV air conditioner gasket is a relatively simple process that anyone with basic DIY skills can do. All you need is a new gasket and some sealant.

The steps involved in replacing the air conditioner gasket in an RV

  1. First, you need to remove the old gasket. To do this, simply pry it off with a flathead screwdriver.
  2. Next, clean the surface of the air conditioner unit where the gasket will be placed. This ensures that the new gasket will adhere properly.
  3. Once the surface is clean, apply a generous amount of sealant to it.
  4. Place the new gasket on top of the sealant and press down firmly to ensure that it’s in place.
  5. Let the sealant dry for 24 hours before using the air conditioner again.

Here are a few tips:

  • Inspect the gasket regularly and replace it if you notice any cracks or damage.
  • Keep the area around the air conditioner unit clean and free of debris.
  • If your RV is stored for long periods of time, cover the air conditioner unit to protect it from the elements.

  • Apply a generous amount of sealant to both the surface of the unit and the back of the gasket.
  • Press down firmly on the gasket to ensure that it’s properly in place.
  • Let the sealant dry for 24 hours before using the air conditioner again.
