Introduzione
If the humidifier function in your ResMed Airsense 10 ventilator has stopped working, a simple replacement of the heater fuse may solve the problem. This guide will also provide you with the information to completely replace the Heater Plate as well.

What size fuse?
good job half done! fuse rating and source please
I can't seem to find this fuse either. Anyone have a link?
Found the Zephyr Micro (referenced by jb5294 above) on Amazon. Came in a pkg of 10. They're larger than the 1 that blew, but will fit. No readable info on the original fuse, so I can only hope new one continues to work (and will safely blow if necessary).
Thanks for responding to other people's comments. Seriously, why not share info about the fuse? This is basically a half assed repair.
Fed up trying to find thermal fuse rating online so I took it apart.
The Resmed Airsense 10 thermal fuse rating is 098 C which is logical as the water should never boil (100 C).
Also note that a simple ohm meter logic test determines if good or bad. Place ohm meter leads across thermal fuse (on each fuse lead) and if it beeps, fuse is good still.
RESMED should provide few fuses . It’s such a shame such a mission critical component is not there in the box . At least provide the fuse specification in the user manual .

Big Tip. Do not let tank run dry!!! Dry tank heats up cooking fuse
G7F01093C Is the replacement fuse.
Available on Amazon for about $8. Looks like a slow delivery though (~ 2 weeks).

Where can I buy a new fuse? This one does not look like one I can get at a hardware store.
Yws, please, where can we buy a new fuse? Thanks.
and yes where do you buy a fuse can’t find no where PLEASE @ cityboi53@yahoo.com
Did you get a reply as to where you can buy the fuse?
any idea how can i get the fuse what are the specs and where can i buy one or someone know where to get the whole heating plate
No I haven’t heard on where to buy fuse and I need one or a heater plate and don’t think you can buy ether one . Resmed is a billon dollar company a year and and worth over 300 billon from what I have read. They wanted 400 dollars to fix my machine from using cs in it and it keeps me well but at the same time been told they are the best
The fuse is a Therm-O-Disc G7F01098C which I found by salvaging one from an inherited AirSense 10. Over time the markings on the fuse fade - I couldn’t read the one from my original machine. That particular one is very hard to find, but a G7F01093C should work (5 degrees C lower cutoff shouldn’t matter) and it’s more commonly available.
The G7f01093C is a 25 amp fuse. The G7F1098C is a 5 amp fuse. That’s a rather larger amount of current difference to put into your CPAP before the fuse cuts out.

Graham did a great job with directions and Carl is correct on all counts and his advise on the number is sound as well. I bought the fuse (G7F01098C) online from Newark. Always change the fuse before changing the heater plate and you can test the fuse with a multimeter set for resistance testing on a low scale (ohms, not k ohms or M ohms would be fine). Once the fuse is replaced you can go into “My Options” and scroll down to “Run Warmup” to test the heater. If it works, then use the “Stop Warmup” to end the cycle. I did not research the heater part number since the fuse replacement solved the malfunction.
Use aluminum foil for fuse
Thanks to Graham (instructions) & Carl (part number). But... Can a heater plate stop working for another reason? Mine stopped heating so I ordered a replacement fuse --- easy. But literally the day before the fuse arrived, the heater plate started working again. I read on another board that it could be a bad capacitor (but my experience is that once a capacitor goes, it's gone forever). Unfortunately I did not test the original fuse until I replaced it --- so of course it tested "good". I now have the new "93C" fuse installed & my 7-year-old unit is working fine but I fear that if it breaks again, it would require a more costly repair.
BTW, to clarify... G7F01093C is an acceptable replacement for G7F01098C as originally stated. The only difference is the temperate at which it opens (93 deg C vs. 98 deg C) --- both are 5 Amp fuses. The manual says the max temp on the plate is 68 deg C and cuts off at 74 deg C.
Note minimum quantity + shipping... 1@$1.98 "93C"s at Newark is $12, 38@$1.33 "98C"s at Testco is $66.
Thanks Basil, so helpful.
Update... With either the new or old fuse, the heater plate sometimes stopped working. I called Repap, a company that fixes/sells CPAP parts. They said it could be a loose connection (with the contacts the fuse plugs into) or the heater plate or the main logic board. I did order a heater plate from them (the said it was "refurbished" but it looked new) and so far, so good. (Their parts were reasonable: $29.95 for the refurb'd heater plate and $9.68 USPS shipping.)
BTW, if one wants to by a new Resmed AirSense 10 Autoset that uses LTE/4G cellular (to replace the older ones that only did CDMA and are no longer compatible with cell phone networks), it is still being made but one needs to specify "MyAir" compatible --- not the "C2C" ("Card to Cloud") model. Then one can use one's existing supplies (the masks and tubes for the newer AirSense 11 are not compatible).

This is a thermal curoff fuse, not a standard current limiting fuse. Look at the temperature printed on the body and order from most elecronic supply companies. i.e. Newark Electronics or Allied Electronics. Amazon has some temperatures available.
Toy can get fuses at your cpap supply store .
You can get the fuses at your cpap supply store
Where can you buy this heat fuse at??
It is my question as well. Not sure where to get an identical fuse which is important of course.
There seems to be a lot of different information about the fuse in this post. The fuse that was in my machine was a MICROTEMP G7F01 098C.

They seem weirdly hard to find on any site selling less than 1000 at a time.
Hi my heat plate does not heat everything else works but no alert on screen if the fuse is blowen should a fault be shown on screen-first l will check fuse easy bit first -if fuse is ok what should l check next and how- one last thing if its the heat plate and l change it is it plug and play or is there some calibration needed. Any help will be greatly appreciated-thanks
