Dometic Thermostat Issue

[R3Jones]

I have a Dometic Brisk Air II with single zone thermostat. When placing the fan in "Lo" mode it shuts off when the desired temperature is reached but it should remain on. When the fan is placed in "Hi", it remains on and acts as it should. Anybody else have this issue? Do I have a bad thermostat?

Also, I've tried resetting to factory defaults with the same results.

It sounds like a bad t-stat.
What happens when it's in auto?

Did it just started doing this?

[R3Jones]

Seems to work correctly in auto mode. It just started doing this and I'm not sure if I caused it or just bad luck.

I recently installed a hard start capacitor but I don't think the issue is related.

Yeah, LOW should stay on, not cycle.

though i do not have an answer
i recently had a question of operation with my A/C in relation to the thermostat on my 2015 Puma. i emailed Puma and they responded within 24hrs with an answer to my question. that may be an option that could give an idea of what is happening that may not have been considered...

Try re initializing the t-stat. In the off position, and with the little LED light off, press and hold + & on/off for about 5 seconds or until -- appears.

I had to replace my t-stat today because static electricity took out my lcd screen when I went to make an adjustment. So- touch something metal before you touch that stat.

Yeah I tried that as well. Seems the t-stat went bad.
