Two families of JennAir range
JennAir ranges fall into two groups. The pro-style ranges are 36 or 48 inches wide. They come as all gas or dual-fuel, in RISE or NOIR trim. Their burners are dual-stacked, and the wider ones add a chrome griddle or a grill. The second group is the downdraft range. JennAir built the first one in 1961. It has a vent in the cooktop and a fan below that pulls smoke down and out. Many older Jenn-Air downdraft ranges are still cooking. A range has an oven under the burners. If yours has none, see JennAir rangetop repair. Brand notes are on our JennAir appliance repair page.
Burner faults on a dual-stacked burner
A dual-stacked burner has two levels of flame ports, one above the other. The top level gives the big flame. The lower level gives the simmer. Spills run down into the lower ports and bake hard. Then the simmer flame gaps or goes out. We take the burner head apart and clear both levels. The igniter sits close to the ports. Grease on its tip gives a weak spark that will not catch. One spark module fires every igniter on the range. When it fails, all burners go dead at once. When one switch gets wet, all of them click without end.
Griddle and grill problems
The chrome griddle cleans up easily, but it needs even heat under it. A plate that is hot at the back and cool in front has a burner tube that is partly plugged. A griddle that never shuts off has a bad thermostat. Do not scrape chrome with metal tools or pads. Scratches make food stick, and the plate is a costly part. On grill models we check the igniter, the burner and the grease path when it flares or will not light.
Downdraft range faults
- Fan runs but smoke stays. The filter is full of grease or the duct is blocked.
- Fan is silent. The switch, the motor or a wire has failed.
- Fan is loud and shakes. The blower wheel is out of balance from grease.
- Flame leans hard toward the vent. The fan speed is too high for that burner, or the flame is set low.
- Oven is slow on a downdraft model. The element or igniter is weak, same as any oven.
Some parts for the oldest downdraft ranges are no longer made. We check what is out there before we quote.
Oven trouble in a JennAir range
Dual-fuel ranges bake with electric elements and a convection fan. Gas ranges use a glow igniter and a gas valve. Slow preheat, uneven browning and a door that will not latch for self clean are the usual calls. Our JennAir oven repair page goes deeper on those.
What owners can do first
Wait until the top is cold. Pull the burner caps and heads and wash them. Dry them fully, since water in the ports stops ignition. Set each piece back on its pins. On a downdraft model, lift the vent grille and wash the filter. Check that the range has power. Dual-fuel ranges use a 240 volt breaker. Gas ranges plug into a wall outlet. With a gas smell and the knobs off, shut the supply valve and step outside to call.
Fees, quotes and who we send
We send a licensed and insured tech who has cleared a background check. He carries common igniters, switches and sensors. He checks spark, flame, the griddle, the fan and the oven in one trip. Diagnosis in a home costs $79. Once the repair gets your approval, we waive it. His price is fixed, with labor and parts in it, and he tells you ahead of the first wrench turn. A+ is independent. One family has owned it. We run 6 AM to 9 PM the whole week. Ring before noon and a visit that day is likely.
A JennAir range is worth fixing in most cases. The cabinets, the counter cut and the vent were all built around it. A downdraft range is harder still to swap, since a hood would have to be added. Owners near Houston should begin with our Texas appliance repair page. Northern Virginia, L.A., Chicago and D.C. are served too. Any brand of range is covered at range repair. Tell us the width and whether it is RISE or NOIR. Knobs and grates differ between the two.
