The first visit
$85 diagnostic
We take it off the repair bill once you say yes to the work. BlueStar is a small part of our work, so instead of a typical price we show each job’s real bill below.
Follow the gas: three stops between the pipe and the flame.
Where the maker’s line on a BlueStar rating plate is legible in our photos, it reads Prizer Painter Stove Works; the BWO30AGS and BSP48 plates add Reading, Pennsylvania. The faults our technicians actually wrote up on BlueStar jobs all sat on the gas side of the range, from the oven igniter to a seal at a gas connection.
So that is how this page is laid out, one stop at a time, with a real job at each stop. The three stories come from Los Angeles (90026), Eagle Rock and Santa Monica. Each price shown is what the customer paid in total, the diagnostic included, rounded to $5.
1
Stop 1 · The bake igniter
An oven that wouldn’t come on, fixed on the day it was booked
On an oven like this the igniter has to glow hot before gas is let through to the burner. When it weakens, nothing lights, and the oven simply looks dead.
October 2026Los Angeles 9002630-inch range, four burnersRepaired · about $450
The booking said the oven doesn’t come on. Our technician’s note is three words long: replace bake igniter. The call came in that morning and the new igniter was in by late afternoon, one visit.
The range on the day of the visit: four open burners under continuous grates, five knobs, the amber indicator lit.

Stop 2 · The oven safety valve (dual thermovalve)
A written quote for the valve, and a visit that ended at the diagnostic
BlueStar’s parts store lists the dual thermovalve as the oven’s safety valve. It sits under the oven and opens only once the igniter is hot, so a failed one leaves the oven cold even with a working igniter.
What the part looks like in place: a dual thermovalve on its bracket under a BlueStar RNB488BSS oven, photographed on a Woodland Hills job in June 2025. Red and yellow leads, flex gas line below.
October 2025Eagle RockBWO30AGS double wall ovensEnded at the $85 diagnostic
A pair of French-door gas wall ovens, installed in August 2011 according to the papers the owner kept. To get underneath, the drawer below the lower oven came out. The finding: the oven needed a new dual thermovalve. Our written quote covered one BlueStar dual thermovalve, supplied and fitted.
That repair didn’t happen. The visit ended at the diagnostic, and we refunded everything charged above the $85. Our file doesn’t record why, so we won’t guess.
The two BWO30AGS ovens stacked in wood cabinets, a star badge on each control strip.Lower oven doors open, the drawer beneath pulled out on its slides, wiring showing in the gap.Behind the drawer: a yellow-handled gas shutoff on a flex line, against the back wall.
BlueStar oven cold while the burners on top still light?
Tell us that when you book, along with the model if you can find the plate. Every visit starts with the $85 diagnostic, and that $85 comes off the repair price when you go ahead.
A gas leak on a 48-inch range, and why we left the gas off
This BSP48’s oven is fired by a power burner: a burner with its own blower, pressure switch, ignition control and gas valve, under the oven floor.
July 2026Santa MonicaBSP48, two ovens and a griddleLeak sealed · gas left off · about $220
Booked on June 30 as a BlueStar oven gas leak, closed the next morning. According to the technician’s note, the O-ring seal at the gas connection was replaced to stop the leak, and the gas supply valve was then left in the OFF position: the range was not to be used until the local gas company re-checked it and restored service.
This was not our first visit to this range. Seven days before that call, we had closed a separate job on it: the oven would go no higher than 350 degrees, and during that job we ordered BlueStar part 781003, the power burner’s gas valve. The file for that earlier job has no technician note on what was fitted or whether it cured the 350 limit, so that is as far as we can tell it.
The BSP48 in June 2026: yellow doors and knobs, a griddle between the burners, cast-iron pans on top.Leak visit, under the oven floor: the burner tube bolted at a round flange, the gas valve and its wiring to the right.Same visit: the tube unbolted and pulled back from that flange, old yellow sealant on the flange face.
From the call to the end of the visit
Three write-ups, three different endings.

Not repaired
For a wider yardstick: counting every completed oven and range job in our records, of any brand, 57% were closed no later than the day after they were booked. Of the three BlueStar write-ups above, the igniter job is the only one that ended with the oven back in service the same day.

Three other BlueStar visits sit in our files with no technician note on the repair, so they get photos here and no story. For the Woodland Hills RNB488BSS, the file holds a BlueStar order for part 718901, the dual thermovalve, and the photo under Stop 2; it does not say what was done.
