Re: A/C Freeze Sensor - How do I check a faulty sensor?
Doug, We don't have the 10 button control system, we have the Firefly multiplexer touch screen. The compressor works for exactly 2 minutes after starting and shuts down, but the fan stays on until the a/c is turned off on the screen. There is a delay of around 2.5 minutes to restart the compressor if you turn it off and on again immediately. The compressor always starts but intermittently turns off after 2 minutes if the sensor is installed, but always turns off if the sensor is not installed.3.5KViews0likes0CommentsRe: A/C Freeze Sensor - How do I check a faulty sensor?
The compressor shut off after a few hours this time. Restarted the A/C several times, ran the fan on high, turned the thermostat down - couldn't get it to run more than 2 minutes. Disconnected the freeze sensor, same result. So, I ran the heat pump for about 2 minutes. It did not stop when it reached the set temperature, so I bumped it down more and I finally had to shut it off. After that, the A/C worked fine. I don't see any freezing going on - but there does seem to be a thermostat issue of sorts. I'll probably call Thor and Dometic tomorrow to see whether they can shed light on this.3.5KViews0likes0CommentsRe: A/C Freeze Sensor - How do I check a faulty sensor?
We only have one a/c. We have checked the separation gasket and sealed between the intake and exhaust. If we remove the Thermister from the coil, the compressor starts and shuts off after exactly 2 minutes. We can try disconnecting the plug from the board and see what happens. Once the a/c runs for longer than 2 minutes, most of the time it's good until we shut it down.3.5KViews0likes0CommentsA/C Freeze Sensor - How do I check a faulty sensor?
Our Dometic Penguin II low profile AC/Heat Pump has an intermittent problem. The AC compressor turns off after 2 minutes (almost to the second). The freeze sensor is plugged in and lodged into the coils firmly. This happens both in cooler weather and hot weather. The fan stays on and the compressor stays off until we turn it off and back on. We suspect that the freeze sensor is faulty. How do we check this? The heat pump works fine. This is a new MH and the AC is clean.8.7KViews0likes7Comments
