Frequently Asked Questions
Q: How do I know if my thermocouple needs replacement?
A: Common signs include the pilot light won't stay lit, the water heater won't ignite, or you see error codes on your control panel. A thermocouple that's bent, corroded, or has a broken connection will prevent the heater from operating safely.
Q: Will this kit work on my specific CBS1 model year?
A: This is a genuine Dometic part designed for CBS1 water heaters. We recommend verifying your model number matches CBS1 before ordering. Contact our expert support team if you're unsure about compatibility.
Q: Is professional installation required?
A: While many RV owners complete this replacement themselves, working with gas appliances requires care. The kit includes all necessary components, but if you're uncomfortable with the installation, we recommend having a certified RV technician handle it.
