When refrigerator starts up it spikes the line and devices get triggered.

Where can I find device to put in the refrigerator ac line to kill that
noise ?

Links please.

Thank you !

Much more information is needed for a complete answer. A "Furman" line conditioner with the capacity to handle a motor load will cost well in excess of a new refrigerator that will not have this issue. If the motor-start capacitor is failing, same issue as these are often sealed units. Applicable only to North America, of course.

So, where/what/age/brand/what is tripping, and how?

Otherwise, look up "true RMS line conditioner".

You may try something like this :

3300-joules~ISOBAR6

Hook it to the refrigerator to start with and if you still get devices
tripping, put it on the devices.

Are you sure it is a spike or is it possiable the refrigerator is
drawing enough current to drop the voltage ? A friend had a loose
neutral on his power line. One side would have low voltage and the
other would have high voltage. He had to get the power company to
correct it.

A surge protector has only limited effectiveness on "outgoing" surges. Not none, limited.

** Now you change your story ?

A burst of "noise " is not a voltage drop that can trigger things.

If the thermostat switch has no RC snubber, there is a burst RF noise that can make its way into audio gear as a click or a brief flash or data loss on a TV screen.

IME no plug in device is effective against this.

You need to add or replace the missing/ faulty snubber.


BTW:

Diagnosing your own problem and its cure is not welcome here.

Just describe the problem in detail and leave the rest open.

That was my first thought - wiring issue.

Hook the fridge up to a surge protector.

Surge Protectors are designed to work on incoming power. Depending on the design, they are far less effective with outgoing surges. And, if you have, in fact, a drop in voltage due to a hard-start, the will have no effect at all.

If it's the back EMF from the motor as I assume it will be, then it'll be
a spike, not a surge, and that requires a different approach.

It's more likely a spike from the motor current being suddenly shut-off.
Remember motors are reactive components.

A normal refrigerator motor turn-off doesn't have this effect. This is
not normal, is most likely a wiring-in-the-walls fault. An electrician should
check the power delivered.
