Raypak Thermal Fuse For Model 105A Versa Pool Heater

Raypak Thermal Fuse For Model 105A Versa Pool Heater 005899F

The Raypak 005899F Thermal Fuse is the genuine OEM safety fuse designed for the Raypak 105A Versa gas pool heater. This critical safety component protects the heater from overheating by interrupting the electrical circuit if unsafe temperature levels are detected.

Product Overview

Over time, thermal fuses can weaken due to heat cycles, restricted airflow, or debris buildup inside the heater cabinet. When the fuse opens, the heater will not fire until the fuse is replaced. Installing a new OEM thermal fuse restores safe operation and ensures the heater’s internal components remain protected.
