Air Leaks in Motor Home Doors

Camping is a recreational hobby that may also be a lifestyle for some people. Owning a motor home can make camping easier and more convenient, but motor homes require upkeep just like automobiles and houses. An air leak in the motor home door is one possible problem the motor home owner might encounter. Air leaks make it difficult to cool, heat or maintain temperature in the motor home.

  1. Door Seals

    • Motor homes are generally manufactured from aluminum; this includes the window frames and doors. Motor home doors and windows have rubber seals that can dry out and deteriorate over time, which can cause air leaks. Replacing these seals every few years, as a preventative measure, will save you from having to replace them at an inconvenient time, such as at a campsite where supplies might be inaccessible. Depending on the motor home, the seal may glue into place or will need to be pushed into a groove or track around the door.

    Door Latches

    • Faulty motor home door latches are another cause of air leaks. When the latch isn't completely closed, the rubber seal cannot close tightly around the door frame. Air can then leak around the door. Check the door latches periodically to see if they are operating correctly; in most cases, the latch should click to indicate that it is properly closed. Repair or replace faulty door latches; replacement door latches are available through online RV retailers and at RV supply centers to fit your specific model of motor home.

    Motor Home Windows

    • Most motor home doors are equipped with windows that have rubber seals to keep air from entering and escaping the motor home. Rotted and worn seals can cause air leaks. Inspect the rubber seals for damage and replace them as necessary. Rubber seals often dry out over time, which can lead to cracks and crumbling. Rub a petroleum-based lubricant onto the seals periodically to condition the rubber and save on replacement. Faulty window latches and cracks in the door glass can also cause air leaks. Cracked door glass can be hazardous if left unrepaired; the glass could get bumped and fall out of the door, causing personal injury. Replace any cracked or damaged glass and latches.

    Holes

    • Holes are one of the more obvious causes of air leaks in a motor home door. Even if the hole doesn't penetrate both sides of the door, air can still leak from the motor home, making it more difficult to maintain the temperature inside. If a quick fix is needed for the damage, use a temporary seal, such as duct tape, a metal patch or auto body filler. If the appearance of the motor home is important, take it to a dealer to have the door professionally repaired or replaced.
