How do you know if your receiver is not working well?

For ReSound Quattro’s, the receiver wire is an integral part of the receiver. I seem to recall that a special tool is required/recommended to detach the receiver wire (and receiver) from the body of the hearing aid. If anyone has recommendations on where to get the tool or what to use in its stead, I’d be happy to hear them. But swapping receivers on HA bodies, if you have the tools to do it, would be a good way of distinguishing body circuitry failure vs. receiver failure as tenkan suggested above.

On testing receiver performance, I’ve found that I can do a crude job by playing tones from an Android tone generator app into over-the-hear headphones one ear at a time vs. streaming the same tones one ear at a time to my HA’s. Since both receivers are unlikely to fail to the same degree in both ears at the same time, one ear serves as a “control” or reference point for the other ear, which you may perceive to be doing worse, etc.

If you’re into DIY, you can always use in-situ audiometry as a built-in test of how your receivers (and HA circuitry) is performing. If you’ve had a recent audiogram and your HA’s have been appropriately programmed for that audiogram, the in-situ audiometry audiogram should relatively closely reflect your audiogram done by conventional means - that tests amplification of low-level sound into a range that your hearing can just detect. If you use the in-situ audiometry feature for evaluating the discomfort level of maximum volume sound, that can very grossly test whether your receivers are still capable of producing output so loud it’s uncomfortable. I have moderate-to-severe age-related high frequency hearing loss, both ears are about the same, and sound frequencies across entire range that HA’s typically address is more or less “recoverable.” Such a strategy is obviously not going to work very well for more complicated or much more severe hearing loss and obviously if you can’t play around with DIY, the in-situ audiometry will not be an option. But the tone generator tests initially suggested might at least give you an idea how well or badly your HA’s are currently performing and if you have an essential job, e.g., nurse in an ICU, maybe you could find an audiologist or HCP somewhere in recognition of your dedication to society who would service your HA’s if you can’t figure out and fix your HA’s yourself.

Be sure the wax guard is clean, and when replacing it look closely for a bit of hard wax that may have got past it and can block the sound.

Your initial hearing aid aids must’ve been out of warranty. My audi has changed the receivers for free but under the warranty period.

One of my hearing aids conking out completely while I was doing…nothing, basically, just out shopping. Came home, took it out, let it sit a few hours and I was back in business. A few weeks later, same thing as I was sitting quietly and suddenly realized I wasn’t hearing out of my right ear. Called the Costco fitter, and he said could be wax. So I pulled off the dome, wax guard nice and white, ran a fingernail over the top of the dome - and I was hearing again. Apparently warmth of the ear can cause the wax to soften and gunk things up a bit. Nice to know that sometimes it’s something that simple.

My domes exit through two side-holes in a bump on the end. I too have had total silence cured by fooling with the dome. I think this is why my fitter gave me a piece of plastic fishing line. It may actually be for the tube, but it is a nice fit in the dome exits. (Go to the dollar store and get the strongest readers they have so you can see the hole.)
