Can someone please tell me what the Pressure switch does? I have a Nordyne heater and all it does is click like its heating up and then it doesnt go anymore. I have replaced the blower but it still doesnt turn on. Any help would be appreciated. Thank you.

Hi,

Welcome to the site.

I am going to move this post to the HVAC forums in the Nordyne Repair Forum. Please follow me there. The tech will need more info so to get quicker service please read the posting tips and answer all the questions that are related to your unit.

Thanks,

It closes at appropriate water column pressure to send low voltage signal forward for the ignition process to begin.
