Carbon Monoxide Detector

Question

So my 2 year old Costar carbon monoxide detector went down. Beeps twice for no reason every 30 seconds. I called the company and they are no help. It is a hard wired unit with battery backup. Anyone else have problems with this brand? Should I replace with another hard wired one or just put wire nuts on the exposed wires and go with a regular "battery only" detector??

This is the wall unit in the bedroom, not the detector in the kitchen.

You said it is 2 years old but how long did it sit on the shelf.. Turns out those units often have an "End of life" timer, about 5 years as I recall, and when it times out.. That's what mine did.

I installed an Costar OEM replacement purchased on Amazon. It had a date code showing it was only a few months old. It was a simple plug in installation as the wire harness connector was identical to the old one.

I see that Kidde has a new unit out that has a ten year battery and a readout display for $50. That may not be a bad way to go.

Also blow off the dust and see if they helps, along with checking the battery.
