Dometic A/C Freeze Sensor Questions
I've been having some problems with the front AC. All 3 of my ACs are the original Dometic Penguin 1 low profile 15K BTU heatpump units that have been modified to work with the new CCC2 programmable thermostat. They have been working fine for nearly 4 years.
The first and oldest problem was that the fan would intermittently continue to run even though the compressor stopped (yes it was set to auto). The second (newer problem) was that the compressor would quick cycle. When the compressor shut down there would be an hourglass on the thermostat. The front of the coach would not cool down. We are spending the summer in Taos, NM and it gets hot here.
Dometic suggested that I replace the control board. I did and that took care of the fan running problem but the quick cycle problem remained.
Today, I removed the freese sensor from the fins and just left it dangle. The AC has been running fine ever since and it blows the same amount of air and the same temp air as the other two units. BTW: I watched the unit cycle with the outer and inner covers off, nothing was freezing up as far as I can tell.
I have a couple of questions for your AC knowledgeable people:
I suspect it is a bad freeze sensor... Thoughts?
Will leaving the sensor dangle and running the AC until I can get it replaced hurt anything?
I read that the sensor was supposed to be at the bottom center of the coils. Mine was about half way up on the left side. Could that be the problem?
