Brief History & Importance of the Thermal Fuse

The Pentair Thermal Fuse (475998) is a critical safety feature in MasterTemp and Sta-Rite Max-E-Therm heaters, designed to prevent dangerous overheating by shutting down the unit when temperatures exceed factory-set limits. This fuse helps protect internal heater components, including the heat exchanger, ignition system, and control board, from excessive heat damage.

Over time, factors such as poor ventilation, clogged filters, or scale buildup can cause higher internal temperatures, leading to thermal fuse failure. Replacing a blown thermal fuse restores safe operation and prevents more costly heater repairs down the line.


Installation Tips & Tricks

WARNING: Always disconnect power at the circuit breaker before working on electrical components.

🔧 Step 1: Turn Off Power – Ensure the heater is completely powered down before servicing.
🔧 Step 2: Access the Thermal Fuse – Remove the heater’s front panel to locate the existing fuse.
🔧 Step 3: Disconnect the Old Fuse – Carefully remove the faulty thermal fuse and any wiring connections.
🔧 Step 4: Install the New Fuse – Secure the Pentair 475998 thermal fuse in place and reconnect the wiring properly.
🔧 Step 5: Test the Heater – Restore power and check for proper operation without error codes.

💡 Pro Tip: If your thermal fuse continues to fail, check for restricted airflow, clogged vents, or high internal temperatures, as these could indicate underlying issues.

Incredible prices & free shipping for name brand products, not cheap knock offs! I placed my order on Sunday and received shipping confirmation on Monday! Filters arrived in the original Pentair Shipping carton the next day. Excellent company and service while saving big over the local pool store and cheap knockoff from large online retailer!

Outstanding support! Customer service has prompt responses and solutions to your pool needs. I am very happy with a replacement suction vacuum solution that was suggested. I bought it and it shipped to my home in 3 days. Great job and a pleasure doing business with this pool company.
