An iHealth thermometer is that thermometer that you use to measure someone’s temperature without touching him or her.
This thermometer has one big advantage in that you can take someone’s temperature as you stand a safe distance away – maybe a couple of feet away.
But before you continue reading the rest of this article, you may want to watch first the short video I made which shows how I fixed my iHealth thermometer that won’t work. You can watch the video is below.
To fix this problem, you just replace the AAA batteries. If the problem persists, remove the cover of the thermometer as I did in this video and directly connect the AAA batteries to the thermometer using crocodile clips.
You should also check the power button and inspect any sign of burning on the PCB.
In fact, the manufacturer recommends that you point the thermometer in the direction of the person whose temperature you are taking, and keep a minimum distance of 3 cm between the gadget and the person’s forehead.
Mark you this thermometer uses batteries, and their energy level can sometimes drop too low. As a result, the thermometer won’t work. This cannot be a big problem, can it?
How to Fix an iHealth Thermometer That’s Not Working
However, there is a reason I want to talk about a thermometer that’s not working. For starters, as far as iHealth thermometers are concerned, moisture is an enemy, and so is dust and other forms of dirt.
If you expose this thermometer to these things, it’s likely to either stop working, or begin to give you wrong readings.
This thermometer also has a sensor that you should not touch with your fingers. If you do, you risk contaminating it – another cause for inaccurate readings.
So, what do you do if, despite all your care, your iHealth thermometer stops working? Well, for me the first thing that comes to mind is “battery gone” – and I straightaway move to change the set of batteries.
That’s really the first thing you should do, because if the batteries have been used for a long time, they may require replacement. Make sure you use a pair of AAA batteries, because that’s what iHealth thermometers come with at the time of buying.
Now, with new batteries, your iHealth thermometer should work well. Yet, sometimes they don’t. If I find myself in such a situation, I know I must look elsewhere for the problem.
So, I open my thermometer – just unscrewing its cover. The reason I do this is to check if the PCB – that part where temperature data is processed – has a problem. PCB stands for “Printed Circuit Board”.
Does it appear burnt? That’s one thing you should check. For me, if there’s no sign of burning on the PCB, I conclude there’s no problem in that area. Yet I still want to confirm that.
I take out the thermometer batteries and connect them with some binder or tape, so that it’s like I have one long battery with one positive and one negative terminal.
Then I take a piece of electric supply cable, and use it to connect the batteries’ positive and negative terminals to those of the thermometer.
If the PCB is fine and I move my face close to the thermometer, it will sense my temperature, process it, and display the outcome in degrees – the normal way.
Still, I want to know why the thermometer isn’t working when the lid is on. What I’ve come to learn is that in many cases, the fault is with the battery holder. That’s something I can ignore and still go on using my digital thermometer.
