How to Replace an Infrared Sauna Heater Panel

Infrared saunas rely on multiple heater panels to generate consistent heat. When one panel stops working, the entire sauna experience is affected. Fortunately, replacing an infrared sauna heater panel is one of the easiest and most cost-effective sauna repairs you can perform yourself.

This step-by-step guide from SaunaPartsWorld explains how to safely diagnose and replace a failed infrared sauna heater panel using universal sauna repair parts.

Signs a Sauna Heater Panel Needs Replacement

• One section of the sauna remains cold
• Visible dark spots, cracks, or burn marks on the panel
• The sauna powers on but does not heat evenly
• A single wall panel does not warm while others do

If only one panel is not heating, the problem is almost always a failed heater panel—not the control panel or power supply.

Tools & Supplies Needed

Step-by-Step: How to Replace an Infrared Sauna Heater Panel

Step 1: Disconnect Power

Turn off the sauna and completely disconnect it from the power source. Never attempt sauna repair while the unit is energized.

Step 2: Remove the Wooden Cover

Carefully remove the interior wooden slats or trim covering the heater panel using a screwdriver.

Step 3: Disconnect the Heater Panel

Unplug the heater panel connector from the wiring harness. Pull from the connector—not the wires.

Step 4: Remove the Failed Panel

Unscrew or unclip the defective infrared heater panel from the sauna wall.

Step 5: Install the New Heater Panel

Mount the replacement heater panel in the same position and reconnect the wiring securely.

Step 6: Reassemble and Test

Reinstall the wooden cover, restore power, and turn the sauna on. The new panel should begin heating within minutes.
