Hello,

I am using a kind of single pole switch with an electronic timer to switch a fan in my bathroom. The model and product is 9590 ASPIRE 5-button Preset Minute Timer

After a distribution problem that caused a power surge/ outage, the switch would not power on and the fan would stop powering on through the switch, but still work with a regular non-electronic switch/wire.

I did a lot of tests in different parts of my house and different loads. The timer simply won't power on in the bathroom 1, wether it is switching a fan or an incandescent light bulb. BUT it will work in the bathroom 2, for both types of load. Therefore i conclude that it is not a fan problem (since same issues with other loads) and not a timer switch problem (since the device works fine in bathroom 2). Without using the timer, everything can be powered normally fine in bathroom 1. Therefore it hints me towards the switch having a mechanism that restricts it from working in bathroom 1 but i cannot find the reason.

I am very out of ideas as to what could be causing this behavior

As you should have read when you filled out the entry questions here:

From a logic standpoint, if the switch functions in a different location, it’s something in the location that is wrong. Some electronic devices need a connection to ground in order to function correctly because of needing to deal with Common Mode Noise, whereas a regular switch or the fan itself would not care. So you may have lost a ground connection in the surge. This is where you need a professional electrician.
