Pro Grand and Pro Harmony: the same top, two very different bodies
Thermador sells one cooktop and two ranges. The Star Burner, the five-point sealed burner with its Pedestal Star variant, sits on every Pro range and is the reason people buy them: better flame coverage under a twelve-inch pan than any round burner, and an ExtraLow setting that cycles the flame on and off to hold a true simmer. Below the cooktop the Pro Harmony is a 24-inch-deep range built to sit flush with cabinets, and the Pro Grand is a 27-inch-deep range with a larger oven and, on 48 and 60-inch units, a second oven, a griddle or a grill. They share burners and share almost nothing else in the oven.
The burner platform fails in two ways and both are electrical, not gas. The Star Burner's spark electrode sits close to the cap and collects boil-over residue; a burner that clicks without lighting, or lights on the third try, usually has a fouled or cracked electrode rather than a valve problem. And the ExtraLow cycling is run by a solenoid valve per burner; when the simmer goes full-off instead of pulsing, or pulses and never relights, that solenoid or its control is the answer. Both are same-visit diagnoses with a meter.
The ovens are where the generations matter. All-gas PRG ovens use a hot-surface igniter and a safety valve, and they fail like every gas oven does, through an igniter that glows but no longer draws enough current. Dual-fuel PRD ovens are electric and run through a power relay board and an electronic control that Thermador and Bosch share across the BSH family. When a PRD oven loses convection, refuses to preheat past 250°F, or throws an E-code on the display, the diagnosis is at the board and the elements it feeds. Pre-2015 Pro Grands also have a known habit of a cracked oven light socket that trips the breaker, which sends owners looking for a far more expensive fault.
BSH-family parts, measured diagnosis, one visit where the truck allows
Thermador parts move through the Bosch distribution network, which is fast on current Pro Grand and Pro Harmony models and slow on the pre-2015 platform. We carry the parts that fail most: Star Burner electrodes and spark modules, ExtraLow solenoids, oven igniters and sensors, door hinge kits. Relay boards and control modules for dual-fuel ovens come through distribution in two to four business days, and we tell you the lead time at the quote, not after.
Every diagnosis is measured. Igniter current against spec on gas ovens, relay actuation and element resistance on dual-fuel, spark output and electrode isolation on the cooktop, solenoid coil readings on ExtraLow faults. The $59 diagnostic is free when you approve the repair, every part carries the 90-day parts and labor warranty, and we log the repair against your range so the history travels with it.
Thermador range repair — failures we see.
Documented from the platform, not a brochure.
A fouled or cracked spark electrode nine times out of ten. The five-point burner puts the electrode close to the cap where boil-over residue collects and eventually insulates it, or heat cycles crack the ceramic. We clean or replace the electrode and check the spark module output on the way, same visit from truck stock.
The simmer setting cycles the flame through a solenoid valve on each burner. When the solenoid sticks or its driver fails, the burner goes full-off and never relights, or pulses erratically. Coil reading with a meter settles it; replacement is a same-visit part on current models.
The igniter glows and the owner assumes it works, but its current draw has fallen below what the safety valve needs. A two-minute amp-clamp test confirms it. Truck-stock replacement and the most common Thermador oven repair we do.
The power relay board or the element it feeds. A PRD that stalls at 250°F, bakes on one element only, or drops convection from the menu is a board-and-element diagnosis with a meter. We confirm which failed before ordering, because the board costs ten times the element.
Thermador's electronic control reports a sensor out of range, a door lock fault on self-clean models, or a communication error between the control and the relay board. Each code points to a specific test. Tell dispatch the code and the technician arrives with the likely part.
A known habit on older Pro Grands. The halogen oven light socket cracks with heat cycles and shorts to the cavity, tripping the breaker mid-bake. Owners are often quoted a control board. It is a $150 socket, and we check it first on any Pro Grand that trips.
The oven sensor drifts out of its resistance curve, or the heavy Pro Grand door has dropped on its hinges and bleeds heat at the top. We measure the sensor, check the door, and verify with a probe before we leave. Dual-fuel controls also carry a calibration offset we can set.
The electric griddle runs its own element and thermostat; the gas grill has its own igniter and valve. Each is a distinct subsystem from the burners, and each is serviceable with parts a few days out at worst.
Typical Thermador range repair costs.
| Repair | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $59 | Free with repair |
| Star Burner spark electrode, clean or replace | $180–$340 | Most common cooktop repair; truck stock |
| Spark module | $260–$430 | When the module itself has failed |
| ExtraLow simmer solenoid | $220–$390 | Per burner; coil-tested first |
| Oven hot-surface igniter (PRG) | $250–$400 | Most common gas oven repair; truck stock |
| Oven temperature sensor | $200–$350 | Probe-verified calibration check included |
| Dual-fuel relay or control board (PRD) | $450–$820 | Only after meter confirmation at the board |
| Oven light socket (breaker-trip fault) | $140–$240 | Checked first on pre-2015 Pro Grands |
| Door hinge kit and gasket | $300–$520 | Pro Grand doors are heavy; restores seal and bake accuracy |
| Griddle element or grill igniter | $280–$520 | 48 and 60-inch units |
Typical parts-plus-labor ranges for South Florida jobs on 30 to 60-inch Thermador Pro Harmony and Pro Grand ranges; 48 and 60-inch double-oven units run higher on oven-side repairs. Written quote after the $59 diagnostic, free if you approve the repair. 90-day parts and labor warranty.

Thermador range repair — questions we get
My Thermador Star Burner clicks but will not light. What is wrong?
Almost always the spark electrode, which sits close to the burner cap and collects boil-over residue until it stops sparking, or cracks with heat cycles. Cleaning or replacing it runs $180 to $340 and closes the same visit. If every burner clicks with the knobs off, that is a leaking switch instead, and we isolate which one.
Why does the ExtraLow simmer go out instead of cycling?
Each burner's simmer runs through a solenoid valve that pulses the flame. When the solenoid sticks or its driver fails, the flame goes full-off and does not relight. We read the coil with a meter and replace the solenoid, $220 to $390 per burner.
My Pro Grand trips the breaker when the oven is on. Is it the control board?
On pre-2015 Pro Grands, check the oven light socket first. It cracks with heat and shorts to the cavity, and it is a $140 to $240 fix. Owners are regularly quoted a board for it. We test the socket before we test anything expensive.
How much does Thermador range repair cost?
The common repairs, electrodes, igniters, solenoids, sensors and hinges, land between $180 and $520 with parts and labor. Dual-fuel relay and control boards run $450 to $820 and are only quoted after meter confirmation. Against a $9,000 to $20,000 replacement, repair wins in nearly every case we see.
Are you an authorized Thermador service center?
No. Berne is an independent service company, not affiliated with Thermador or BSH Home Appliances. For a range still under factory warranty, factory-designated service protects the coverage and is the right call. Out of warranty, an independent shop with deep Thermador experience is faster and cheaper, and we will say so if your case belongs on the other side of that line.
