Does a circuit board with an SPD protect against internal surges?

So is that better than using something like this? Does a circuit board with an SPD protect against internal surges? - https://www.electriciansforums.net/threads/does-a-circuit-board-with-an-spd-protect-against-internal-surges.208688/#post-1833953

Hello!

I'm struggling to find an answer to this question online. I'm new here btw - I'm a DIYer with a physics degree

Currently when my fridge motor turns off, I get a transient voltage spike on other devices plugged into the same circuit (i.e. an internal surge)

If I upgraded my circuit board to include an SPD, would this help prevent this and dissipate the energy? Or does it only protect against lightening strikes and similar external spikes?

Thanks!
Oscar

Although a surge protector is a good idea to protect against unexpected surges that may damage electrical devices,

You seem to have a device with a known fault (fridge) in that when it is switching on/off it is putting electrical surges or noise in the local distribution of your property and/or electrical noise passing through the air.

Really you should be looking to remove the interference at source, not trying to suppress it after the event.
A new fridge might be the best option for you.

Woops wrong link! I meant, would it be better than something like this? https://cpc.farnell.com/pro-elec/97...9208&s_kwcid=AL!5616!3!491098866149!!!network}!887692084055!&gclid=CjwKCAjwt52mBhB5EiwA05YKo2SXjW3fdgcvkcsr8fXBp_AAv5hVnTBgEvoqPL_B871SMrQlZj-vxBoCnXQQAvD_BwE

If a car that has been working fine for years suddenly starts pouring smoke out and disturbing the neighbours, do we

A.. Find a way to mask the neighbours from the smoke using shields and filters so they don't notice?
or
B.. Fix the car so it no longer disturbs them with plumes of black smoke every time you start it up in the morning.

Yes good point taken... Fridge will be replaced in a few months, but keen to protect against damage in the meantime, and in general upgrade the electrics here! Thanks

Have you considered a repair rather than replacement, this problem could be the result of a simple component failure.

The fridge is already rusty on the outside etc so i think it's part its shelf life...
