We've got a great stove, at least in theory. A Thermidor RDFS30 gas slide in range from the mid 90's. For some time now they have not manufactured replacement parts. It turns out the LED display on the oven control module (part number 486752) is dim. Hardly readable even in the dark. The time is readable but the oven temperature is not. I see some of these modules used on EBay for over $600. Yikes! And one post for the wrong part. Scary. We'll need to re-do the kitchen eventually, and we've dodged a fridge replacement so far this year. So, I'd like to get this fixed until we have time to think about a re-do. An equivalent LG model is on sale for $1299. Online I see two companies who will repair the unit and ship it back for about $200. Also, there is a 'repair kit' available, but the repair kit handles other issues with the control board - not the dim LEDs. The deal with my partner is, if we can use the cooktop, I can disable the oven for a week. To access the control module, first I had to turn off the power and unscrew the brass fittings under each burner.
But when I take the control board out, it seems the gas does not flow to the burners.
Bummer. I was scratching my head looking at the schematic, there are two gas solenoids but four burners.
It turns out that this range has two burners that cycle off and back on to reduce the temperature on an ultra low setting. So those two burners will not work without power, but the other two will.
On the first go-round, I disassembled the cook top and discovered that two of the ignitors were loose.
I ordered circlips ($2.50 ea.) to secure the two ignitors. I installed the clips but waited for a convenient moment to remove the control module.
