The burner runs hot for a long time rather than in bursts. It sits directly beneath the food rather than beside it, so everything that comes off the food lands on it. And the flame is hidden under a heavy grate, which is exactly where a flame sensor has the hardest job. Those three facts account for most of what we are called out for. ### What actually goes wrong - **Lights, then goes out under load.** The flame sensor, carboned over, telling the control the burner has quit. - **Uneven searing.** Blocked ports at the end of the grate that gets used, or a grate that is warped or upside down. - **Igniters that click and click.** They live in the drip line; in this climate they also live in salt air. - **Grates and radiants gone soft.** Consumable, replaceable, and worth replacing before they take the burner with them. ### Indoor module or outdoor cabinet — say which when you book A grill module in a Professional range shares the range’s gas supply, its controls and its ventilation, so a module problem is often a range problem and the visit is planned as one. An outdoor cabinet is its own appliance with its own supply and its own weather. The two share a parts vocabulary and almost nothing else, and knowing which one you have before we arrive is the difference between one visit and two. ### What to have ready when you call The model number from the plate, whether the grill is a module in a range or rangetop or a cabinet outdoors, whether it is natural gas or propane, and what it does — will not light, lights and quits, or sears unevenly.

That is nearly always the flame sensor rather than the igniter. A grill burner sits under a heavy grate that shields it, and the sensor has to see a flame it can barely reach; carbon on the sensor tip is enough to make the control decide the burner has gone out and shut the gas. Cleaning the tip is a real repair and it is the first thing looked at. ### One end of the grate sears and the other does not. Look at the burner ports along the cold end before assuming anything electrical. A grill burner runs directly under everything that drips off the food, and the ports at the busy end of the grate block first. It is also worth checking that the grate is sitting flat and the right way up — a warped or inverted grate changes the gap to the flame and does it unevenly. ### Can a grill module be retrofitted into my rangetop? On this maker, modules are matched to the deck they were designed for, so the honest answer depends on which generation your appliance is. Send the model number from the plate and we will tell you what the deck takes. What we will not do is fit a module the appliance was not built for: the gas rate and the cutout are part of the design, not a preference. ### My outdoor Thermador grill still works. Can you keep it going? Usually yes, and in this climate that is worth saying plainly: salt air and humidity take the burners, the grates and the igniters long before anything electronic gives up, and all of those are serviceable parts. Where a specific part is no longer made we say so before any work rather than after — and on a cabinet that has spent fifteen years outdoors in South Florida, that conversation is part of the visit. --- **[Read full article: Grills & grill modules](https://thermadormiami.support/appliances/grill/)**
