Full Diagnostic Testing
We test igniter amperage, gas valve resistance, thermocouple output, and flame sensor response with a multimeter and clamp meter. You get the actual finding, not a guess, plus a written quote before any work starts.
When a burner clicks but never lights or your oven smells like gas, you need Gas Appliance Repair in Rockville from a crew that treats gas lines with respect. We diagnose igniters, safety valves, and thermocouples on Whirlpool, GE, Samsung, LG, and Bosch units across Montgomery County. Same-day gas appliance service in Rockville MD, upfront pricing, and a workmanship warranty on every repair.

Gas Appliance Repair in Rockville covers everything that carries a gas line into a kitchen or laundry room: ranges, wall ovens, cooktops, dryers, and the ignition and safety systems that keep them running. We test the gas valve, spark module, igniter, thermocouple, and flame sensor with a multimeter and clamp meter, then confirm the fix with a leak detector and thermometer before we pack up. A weak igniter draws the wrong amperage, a dirty orifice starves the burner, and a failing safety valve shuts the whole unit down. We find which one it is instead of guessing.
Most calls we run in Rockville come from homes built in the 1960s through the 1990s, where original gas shutoffs are stiff and burner assemblies have years of grease baked on. Winter is our busiest stretch. A gas oven not lighting repair in Rockville MD turns into a holiday dinner problem fast, and a dryer that won't heat leaves wet laundry stacked in the hallway. If you're searching for gas appliance repair near me Rockville, we answer the phone, tell you the arrival window, and show up inside it.
Every gas appliance call starts with a full diagnostic and ends with a tested, leak-checked appliance. Here's what's included as standard, and what we'll quote separately if your job needs it.
We test igniter amperage, gas valve resistance, thermocouple output, and flame sensor response with a multimeter and clamp meter. You get the actual finding, not a guess, plus a written quote before any work starts.

These are the two most common gas appliance failures we see in Rockville. We stock igniters and thermocouples for Whirlpool, GE, Samsung, LG, Maytag, Frigidaire, and Bosch, so most swaps finish in a single visit.
Grease and debris clog burner ports over time, causing uneven flames and delayed ignition. We clean the orifices, clear the ports, and verify a steady blue flame on every burner before we call it done.
When a control board or gas valve fails, we replace it, reprogram where needed, and run a full cycle test. We carry boards for major brands so you're not waiting a week for a part to ship.
Before we leave, we relight the appliance, check flame color and height, leak-test every connection, and confirm the safety shutoff works. You get a walkthrough of what failed and what we did to fix it.
You call +1 (301) 368-0217 or book online. We ask what the appliance is doing, the brand, and your ZIP so we can load the right parts. You get a two-hour arrival window and a text when the tech is en route. Most Rockville calls get a same-day slot.
The tech shuts off the gas, pulls the unit out on an appliance dolly, and runs tests with a multimeter, clamp meter, and leak detector. We check igniter amperage, gas valve resistance, and flame color. Diagnosis takes 20 to 40 minutes and you get the finding in plain English.
We hand you the repair price and the parts needed. You approve or decline, no pressure either way. If it's a $600 fix on a 15-year-old range, we'll say so and talk through replacement math. Nothing gets done until you say go.
We replace the failed part, reseal connections, and torque gas fittings to spec. A typical igniter or thermocouple swap takes 45 to 90 minutes. Bigger jobs like a control board or gas valve can run two to three hours. We keep the work area covered and clean up after.
We relight the appliance, check every burner, and confirm the flame is blue with no yellow tips. A leak detector goes over every joint. Then we walk you through what failed, what we did, and how to keep it running. You get the warranty terms in writing before we leave.

We measure igniter amperage, gas valve resistance, and control board voltage to pinpoint the failed component instead of replacing parts by guesswork.
Every gas joint we touch gets checked with an electronic leak detector. We confirm zero readings before relighting the appliance and before we leave your home.
Used on gas pressure checks and refrigerant systems to verify the appliance is running at the manufacturer's specified pressure, not just 'close enough.'
Gas ranges, wall ovens, and stacked laundry units are heavy and awkward. We move them safely without scratching floors or damaging cabinets.
Manufacturers use a mix of fastener types. Having the full set means we open the unit cleanly and don't strip screws that hold burner assemblies and panels.
We verify oven calibration at multiple set points and confirm dryer drum temperature reaches spec during a full heat cycle before calling the repair complete.

A homeowner in Twinbrook called because their gas oven took 90 seconds to light and sometimes didn't light at all. The igniter glowed but the safety valve never opened, so raw gas built up in the cavity before the unit shut down.
After: We measured igniter amperage at 2.1 amps against a 3.2-amp spec, replaced the igniter, and confirmed the safety valve opened in 38 seconds. The oven reached 350 degrees in under 12 minutes and held temperature through a full cycle. Total cost was $295.

A King Farm family had a gas dryer that ran full cycles but left clothes damp. They'd been running every load twice for two weeks, and the dryer was starting to smell hot near the back panel.
After: We tested the igniter, thermal fuse, and gas valve coils with a multimeter and clamp meter. The valve coils were out of spec, so we replaced them and ran a full heat cycle. Drum temperature hit 135 degrees within 8 minutes and stayed steady. Repair cost $240.

A homeowner near Rockville Town Center smelled gas near their range after a recent move. The previous install had a fitting that wasn't torqued to spec, and the leak detector picked up a reading at the supply connection.
After: We shut off the gas, resealed and torqued the fitting, and leak-tested every joint on the supply line and at the range. All readings came back zero. We relit the burners, confirmed blue flames on all four, and verified the safety shutoff worked. Total was $185.

We clean or replace the orifice, dry or replace the spark module, and test every burner individually. If the igniter is cracked, we swap it and confirm a strong blue flame on all positions before finishing.
We test all three components with a multimeter and clamp meter, replace the failed part, and run a full heat cycle to confirm the drum reaches temperature. Most dryer repairs finish in one visit with parts we carry on the truck.
Shut off the gas valve, ventilate the area, and call us. We leak-test every joint with a leak detector, tighten or replace the fitting, and confirm zero readings before we relight the appliance. Safety verification is included in every call.
