I tried prying the start button off my machine and all I had to do was take a q-tip with a little rubbing alcohol on it to wipe off the contacts and my machine works like a charm again!

THANK YOU!!

Hi there fergi
Thanks to your information my totally stressed out tenant can have a peaceful rest tonight!!! His S8 packed up as he went to bed last night with highest temperatures recorded (Zululand, South Africa) this year, 33 degrees Celsius plus 7 degrees added for high humidity, running between 90% and 100%. You are a life-saver, got it going in under one minute after following your advice! At age 55, stage 2 diabetic and sugar-levels at danger levels, you probably saved his life tonight! Thanks again, man, and may God bless you for sharing...

You get my landlord of the year award

Hi,
I have had the same problems with my VPAP IV ST Resmed machine purchased in 2008.

I followed forge's instructions and, hey presto, the START button now appears to be working properly.

Many thanks for the advice.

I lack confidence doing the suggestions, but I am determined to give it a try especially after forcing an approximate price for the repair, do not know how those who decide the pricing sleep at night.

I have read some pulled out the on off button, others removing the face plate

but one person ruined the rubber seal when pulling out the button

as it only involves the button I would like to just access the button but if I damage the rubber seal resmed gets my business

as for undoing the face plate can I damage anything while trying and is there much force involved

I am confused regarding the filing down method. I assume the 2 prongs have a form of coating , when filing are you reshaping the prongs or are you filing away the coating and exposing I assume just wire

appreciate as much detail as possible, ta

Rule of thumb: factor in age of machine and cost of repair versus advantages of new technology
and anticipated future life expectancy. (The machine's and YOURS)
IOW--bite the bullet and buy a new machine, or even a less ancient used machine.
It is your health, after all.

+1, Save the old one you now have working again for backup. Jim

Or you could apply the PaieRider Methodology:
postulate 1: I've got some time on my hands and I'm a little bored of posting on CPAPtalk.
postulate 2: I've got a machine here (one of many) and I wonder how it works or what its limits of endurance are. etc etc
postulate 3: I'm getting out my Torx and needle-nose pliers now and having a go.
postulate 4: Damn the torpedoes

Necessity is not the mother of all invention.
Sometimes curiosity just gets an itch and goes after it.

thanx very much for the tip....................now my machine works great

See if your supplier will order the keypad for you and install it yourself. MSRP is $34.53, see if you can get it at dealer's cost and save a lot more $$.
Part# is 19323

Thanks to Fergi! Taking off the rubber on/off switch and lightly filing the contacts with an emery board really works. I've been plugging and unplugging my unit since this switch stopped working. Try it you may have luck like I did and didn't have to spend money to have a shop fix it.

rubbing a pencil eraser on the contacts will remove the oxidation while doing far less damage to them. Try it

Try the eraser BEFORE any sanding or scratching, it's much more gentle.
