Frequently Asked Questions
How do I know if my thermal fuse has blown?
If your Dometic refrigerator suddenly stops cooling but the interior light still works, or if the fridge won't power on at all, a blown thermal fuse is a common cause. The fuse is a one-time safety device that cannot be reset—it must be replaced.
Can I replace the thermal fuse myself?
Yes, this is a straightforward replacement for most RV owners. The fuse assembly is typically located near the compressor or cooling circuit. Consult your Dometic refrigerator manual for the exact location, or contact our support team for guidance.
Why did my thermal fuse blow?
Thermal fuses blow when the refrigerator overheats, which can happen due to blocked ventilation, ambient temperatures above 110°F, a failed compressor, or a refrigerant leak. After replacing the fuse, check for these conditions to prevent future failures.
