Frequently Asked Questions
How do I know if my expansion valve needs replacement?
Signs of a failing expansion valve include weak or no cooling output, inconsistent temperature control, ice buildup on the evaporator coil, or hissing sounds from the AC unit. If your Dometic KRA025 isn't maintaining temperature like it used to, the expansion valve is a common failure point.
Is this a direct replacement for my KRA025 unit?
Yes, this is an OEM Dometic part designed as a direct fit for KRA025 air conditioning systems. No modifications or adapters are needed — simply remove the old valve and install the new one.
Do I need to recharge my AC system after installing this valve?
We recommend having a qualified RV technician handle the installation and any necessary refrigerant recharging. Proper evacuation and recharging of R134A systems requires specialized equipment and expertise to ensure your system operates safely and efficiently.
