I have a timbales Seaward
Princess 3 burner LPG range which was installed in 2001.
I have lately discovered that the burner knobs won’t turn off when the thing gets hot. I can adjust the flame height, but cannot turn past the IGN point. No matter how hard I push the knob, it is as stuck as if I hadn’t pushed it at all. I have tried pushing hard, and also tried pushing the knob not-quite-all-the-way in.
Workaround is to shut off LPG and allow the range to cool. Everything works fine next time. Happens infrequently, as I do mostly quick cooking
. There was no problem last time someone made a batch of pancakes, for example.
* I first noticed this after running the oven
for “a while”. Cannot turn off any burner one might turn on.
* Recently, I found that running a burner at medium heat for “a while” also makes that burner’s knob stick.
Has anyone else had this problem? I imagine it has to do with thermal expansion, but don’t know why it has arisen with age. Is there some particular point where wear and/or accumulated debris is a problem when the system heats?
Trying to avoid disassembling the stovetop too many times, as that damages the dielectric “fish paper”.
Thanks in advance for any experience you may have had investigating this problem.
