Tonight's roast dinner was in serious jeopardy when Jayne in her wisdom managed to lock the oven door open...
Long story short(ish), this morning she'd set the oven to 'self-clean' in an attempt to avoid the usual smoking that happens when the oven's whacked up high for the roast teddies... only problem was she went and opened the door just as it was locking (to check there was nothing in there that wouldn't survive the cleaning cycle) and then it was too late - door locked open, the lock light flashing in a most offensive tone of voice and nothing at all happening in the oven whatever knobs were twiddled. Oops!
The helpline was of course useless - nobody there - they were all probably off having their own roast dinners. >:[ Clearly emergency oven situations should be planned well in advance so as not to happen on a Sunday.
So, Google to the rescue... a few promising sounding sites were no help at all, and then came "The Appliance Guru", who seemed to offer lots of pointers to people whose ovens were locked shut (the norm I guess) but nowt that was any use to us with our somewhat ancient and decrepid old oven... the solutions talked of 'keeping buttons pressed in for 30 seconds'... what **$$##@@ buttons Jayne screamed at the computer?? We only have knobs which fall off if you do anything other than turn them slowly with due care and attention.

So, armed with a trusty wire coat hanger, Jayne had a good old go at the troublesome door lock which was sticking out like it was blowing a raspberry. Sadly it was to no effect other than to inspire lots of cursing under the breath and sending lots of manky bits of burnt-on goodness knows what flying across the kitchen. Eeeew!
Unplugging and plugging back in is usually a good bet for most electrical problems (well, it is on planet pink anyway) but did nothing either. Grrrr.

Finally, after more trawling on the internet, Jayne found
http://www.appliance411.com/com/ and deduced it was a solenoid locking mechanism and that there should be a little switch on the inside of the oven that detects if the door is open or shut.
Breaking into an excited trot Jayne dashed back to the kitchen, found the very switch, pressed it and... whirring as the latch moved to the right... hang on, the door still won't close... pressed it again and whirring as the latch moved to the left... BINGO! The lock light went off and the door closed and all was well once more. :))
Disaster averted and oven cleaning now underway... Fingers crossed for a yummy roast later on.
