I have a Danby propane fridge that has served me remarkably well for over 10 years. I service it myself by brushing out the tube etc. Last year it started shutting off when we were away. This posed a problem as we leave food in there. Last week we opened cottage and fridge was good for 14 hours roughly and then it was off. I restarted it and it lasted a couple hours. I have the Danby M9SS6 wall mountedCO2 detector wired to fridge. I need to sort this issue out so does anyone know if these detectors need to be replaced after a certain period of time or is there anyway of bypassing it altogether? The detectors run anywhere from $150 to $250 and I would hate to replace it to find that it was not the problem.Does anyone have any ideas what else could be the problem?

I store it on my sun porch and leave the outside window open a crack and keep fresh air accessible, and cottage doors open.

the usual home CO detectors have a replacement time of about 5 years IIRC. Don't know about that fridge though. Most likely hard to bypass unless you know hpw the 'tronics work.
any drafts that could be affecting the flame? has the burner and flue been cleaned lately?

Solved the problem this weekend. The Co2 detector needed to be replaced but the cost was north of $200.We bypassed the detector by ctting the wire and wiring it directly to a 9V battery and it works.

So, the CO detector was wired into the fridge controls? I presume that was in order to ensure your safety. I hope you have another CO detector/alarm in the cabin to ensure your safety?

The fellow I spoke to in Arizona said "you must be from Canada because I have sold over 3000 of those fridges without the detector". Co2 should not be an issue with proper cleaning and the fact I store the fridge on the sun porch with plenty of air flow. The replacement cost is $260 or so, I can get a battery operated one for $20.

The battery sends a 9V charge to the circuit on the fridge and if the detector detects Co2 it stops the current thus shutting off the fridge. So we cut the wire to the detector put the 9V on the wire directly from the circuit totally bypassing the detector, this gives it a constant 9V charge to the circuit. We bought a cheap battery operated Co2 detector for a warning for Co2, this was a much better option than the $200 plus for the detector. If you keep the exhaust tube and fridge clean Co2 should not be an issue.

I see that this is an old post but just wondering if this method worked out for you? Or anyone else that may have a work around. I have the same problem with my propane fridge and was considering doing the same thing.
Thinking of putting a volt meter on the output of the co2 detector to the fridge and matching the voltage with a step down converter off my 12 volt solar circuit. Might work slick. ( I have another stand alone co2 detector in use).
Thanks for any suggestions or advice from anyone...
