2. Electrical System Failure

Your Allegro Red can suffer from an electrical system failure in its various parts, including charging sockets and lighting. Here is how you can trace and handle the issue.


The system failure is caused by the following things:

  • An insecure electrical joint: Because of variations in temperature, electrical connections often become slack. In the end, it causes the electricity to go out.
  • Problems with battery: A lack of power to the main electrical system might result in a malfunctioning inverter or bad batteries.

You can fix it by following these methods:

  • Look for all electrical links: Verify the safety and integrity of all electrical connections. Clean them regularly to ensure smooth operation. You may use a contact washer or rust preventative for this purpose.
  • Batteries and the inverter should be inspected: Ensure to monitor your RV’s cells and inverter. Whether it can be mended or not, damaged batteries should be replaced as soon as possible.
  • Distribute the load correctly: Be careful not to overload any one circuit by applying equal pressure everywhere. Keep an eye on the overall amount of electricity being consumed to prevent overloads and tripped breakers.

3. Water Leaks

Water leaks can lead to serious issues in your Tiffin Allegro Red 33AA like rot, mold growth, and structural issues.


The following things are the culprits behind this issue:

  • Faulty seals: Water can leak in during rainstorms or after you wash the RV because the seals around the doors or windows vents have worn down over time.
  • Deteriorated plumber’s joints: Bad connections between pipes, fittings, and taps are another common source of leaks.
  • Leaks from cracked water tanks: Water might get into your RV if any of the tanks are damaged.

4. Faulty Air Conditioning

During tough and hot weather, faulty air conditioners can cause a lot of problems.


The ac malfunctions due to the following reasons:

  • Dirty air filters: Like other air conditioners, your Red 33AA AC might become less efficient if dust builds up on the filters.
  • Damaged compressor: A malfunctioning motor may affect the air conditioning power of a compressor.
  • Refrigerant leaks: Refrigerant leaks are harmful to air conditioners and reduce their cooling capacity.

In order to get rid of the malfunctions, you can do the following:
