Troubleshooting Freezer

Hi all,

I recently defrosted my Vitrifrigo Freezer. I shut off power with the thermostat switch, let the ice melt, cleaned up and turned the unit back on.

No go. The unit has not come back on. I checked to be sure power is getting to unit, it is. I tested the power coming to thermostat control inside freezer, it seems to be getting power (5 v). I jumped the thermostat connectors to see if it would start compressor - no response from compressor.

So, now I'm wondering what to do next before I call a pro.

Any ideas would be appreciated.

Had the same with my fridge last year. Turned out that it had developed a leak, no more gas in the system. To check for this you need a pro, unless you have a fridge with valves for recharging. Mine had not, so it was the pro.

Assuming Danfoss BD50/BD35, you need to connect a LED between the D terminal and +12vdc. Turn the unit on and count the flashes on the led, then look up the diagnostic code our post results here and I can look it up for you.

Re: Troubleshooting Freezer

Check your DC voltage. When you disconnect the compressor power the driver trips into off - (low voltage mode) and when you reconnect it has to 'see' 12+ volts to go back into run mode - (voltage ok).
To check, boost battery voltage. Cheers,

Re: Troubleshooting Freezer

Was it a particularly hot day when you tried to restart the unit? I've seen overcharged systems run quite happily while the box is cold, but refused to start on a hot day due to excessive refrigerant head pressure. When you're only talking about 2-3oz of total r134a charge, it doesn't take much to upset the balance.
