How to Repair an Infrared Sauna: The Complete Step-by-Step Sauna Repair Guide (2025)

An infrared sauna is designed to last many years, but over time, electrical and heating components wear out. If your sauna is not heating, the control panel has stopped working, or heater panels no longer function, you do not need to replace the entire unit.

More than 90% of sauna failures can be repaired with proper diagnosis and high-quality sauna replacement parts. This complete guide by SaunaPartsWorld explains exactly how to repair an infrared sauna safely and affordably.


Who This Guide Is For

  • Homeowners with infrared or traditional saunas
  • DIY users looking to repair a sauna themselves
  • Owners of discontinued or unknown sauna brands
  • Anyone searching for sauna repair or sauna replacement parts

Common Signs Your Sauna Needs Repair

  • Sauna powers on but does not heat
  • Sauna will not turn on at all
  • Control panel screen is black or frozen
  • Heater panels stay cold
  • Sauna shuts off mid-session
  • Breaker trips when sauna starts

All of these issues are repairable.


Tools and Sauna Repair Parts You May Need

Basic Tools

  • Phillips and flathead screwdrivers
  • Multimeter (recommended)
  • Needle-nose pliers
  • Smartphone for reference photos

Common Sauna Replacement Parts

  • Universal sauna control panel
  • Sauna power control box
  • Infrared heater replacement panels
  • Wiring harness and connectors
  • Temperature sensor / thermostat
  • Complete sauna repair kit

Step 1: Identify Your Sauna Type and Voltage

Before replacing any component, identify whether your sauna is infrared or traditional and confirm the voltage rating (120V or 220V). Using the wrong voltage can permanently damage heater panels and control systems.


Step 2: Sauna Will Not Turn On (No Power)

If the sauna shows no signs of power, first check the outlet, breaker, and power cable. If external power is confirmed, the problem is usually internal.

Likely Causes

  • Failed control panel
  • Burned power supply or transformer
  • Internal fuse failure

Solution: Replace the sauna power control box or install a universal sauna controller.


Step 3: Control Panel Not Working

Symptoms include a black screen, unresponsive buttons, random shutdowns, or error codes.

Why Control Panels Fail

  • Heat exposure
  • Moisture intrusion
  • Aging circuits

Fix: Install a universal digital sauna control panel compatible with most major brands.


Step 4: Sauna Turns On but Does Not Heat

This is the most common sauna repair issue.

Diagnosis

  • Some heaters work: replace failed heater panels
  • No heaters work: power control box or relay failure

Solution: Replace infrared heater panels or the sauna power control box.


Step 5: Sauna Heats Slowly or Unevenly

Aging heaters, weak power output, or faulty temperature sensors can cause slow or uneven heating.


Step 6: Sauna Shuts Off Automatically

This is often caused by overheating relays or faulty temperature sensors, especially in saunas over 7–10 years old.


Step 7: Breaker Trips When Sauna Starts

This indicates an electrical fault such as shorted heaters or damaged wiring. Always unplug the sauna before inspecting internal components.


When to Use a Universal Sauna Repair Kit

If your sauna is older, discontinued, or has multiple failing components, a complete sauna repair kit provides the most reliable long-term solution.


Sauna Brands Compatible with Universal Repair Kits

  • Health Mate
  • Sunlighten
  • Clearlight
  • JNH Lifestyles
  • Dynamic / Maxxus
  • Golden Designs
  • LifeSmart
  • Costco OEM saunas

Cost of Sauna Repair vs Replacement

Repairing a sauna typically costs 80–90% less than purchasing a new sauna.


DIY vs Professional Sauna Repair

Most sauna repairs can be completed by homeowners using plug-and-play components. Professional help is recommended for hardwired or 220V systems.
