The Dometic K8949-00 is a 2-pack of 4 amp slow blow fuses designed specifically for Dometic RV refrigerators and cooling units. These fuses protect your refrigerator's control board from electrical surges and overcurrent conditions. If your Dometic fridge has stopped working or won't power on, a blown fuse is often the culprit — and this kit provides two replacement fuses so you have a spare on hand.

Frequently Asked Questions
How do I know if my Dometic refrigerator fuse is blown?
If your refrigerator won't power on at all, won't switch between gas and electric modes, or the control panel is completely dead, a blown fuse is a likely cause. You can visually inspect the fuse — a blown fuse will have a broken wire visible inside the glass tube, or the glass may appear darkened or cloudy. Always disconnect power before checking fuses.
What causes Dometic refrigerator fuses to blow?
Common causes include power surges from shore power or generator issues, short circuits in wiring, failing heating elements, defective thermostors, or control board problems. If your replacement fuse blows immediately or repeatedly, there's likely an underlying electrical issue that needs diagnosis before continuing to replace fuses.
Can I use a regular automotive fuse instead of this Dometic fuse?
While some automotive fuses may physically fit, it's critical to use the correct slow blow type and exact amperage rating specified by Dometic. Regular fast-blow fuses may trip during normal compressor startup cycles, while higher amperage fuses won't protect your control board properly. Always use the OEM-specified replacement.
Where is the fuse located on my Dometic refrigerator?
The fuse is typically located on the control board assembly, which is usually accessed from the exterior side panel of the refrigerator. You'll need to remove the lower exterior access panel to reach the control board. Consult your refrigerator's service manual for exact location, as it varies by model. Always disconnect power before servicing.
