Sauna Repair in Miami, FL

A home sauna is a simple machine until the day it will not heat — and then it is a 240-volt heater, a stack of stones, a controller, and a sensor that all have to agree before you get a single degree of warmth. Berne Appliance Repair services residential electric and infrared saunas across Miami-Dade, Broward, and Palm Beach. Same-day appointments most days, a flat $59 diagnostic that is applied to the repair, and a 4.79-star record across 871 reviews built over eleven years and 29,300+ completed jobs. Whether it is a traditional Finnish heater that has stopped glowing or an infrared cabin throwing a fault code, we diagnose it on the truck and quote it in writing before any work begins.

Brands we service

Our technicians carry parts and training for the home-sauna brands we see most often in South Florida: Tylo, Tylo Helo, Harvia, Finnleo, Amerec, Saunatec, Polar, Scandia, and the major infrared cabin makers Sunlighten, JNH Lifestyles, Dynamic, Clearlight, and Health Mate. We work on both wall-mounted electric heaters and freestanding floor units, plus the digital and analog control packs that drive them.

Common sauna problems — symptom, cause & fix

Sauna will not turn on at all

Usually a tripped high-limit cutout, a failed door/timer interlock, or a controller that has lost power on the low-voltage side. We test the contactor, the limit reset, and the control transformer before condemning any board — a $30 reset switch is a very different repair from a $300 controller.

Heater runs but never reaches temperature

The classic cause is one open heating element. A 6kW heater typically uses three elements; lose one and the cabin tops out 40-50°F low while still drawing current. We measure each element’s resistance, confirm the contactor is pulling in all legs, and replace only the failed element.

Temperature reads wrong or swings wildly

Almost always the thermistor/temperature sensor mounted near the ceiling has drifted or the sensor lead has corroded in the humid air. Recalibration or a new sensor brings the controller back to honest numbers.

Controller is dark or showing a fault code

We read the manufacturer fault code, check the ribbon/sensor harness, and verify the contactor is actually switching. Many “dead board” calls are a blown control fuse or a chafed sensor wire, not the board itself.

Breaker trips when the sauna is running

A heating element gone to ground, a water-damaged contactor, or moisture in the junction box. This one we treat as safety-first: the unit stays off until the ground fault is found and corrected.

Infrared panels not warming

Carbon or ceramic emitters fail open, or the power supply / SSR feeding a bank of panels quits. We isolate the dead zone, test the emitter and its driver, and swap the failed component.
