Customer Question
Hello, I have Ruud...

Hello, I have Ruud unit blinking light 4 times indicating pressure switch closed. Any help would be appreciated. Thank you.

Contractor's Assistant: Did you double-check the thermostat? And what about the unit's filters?

What should I check on the thermostat? The filters have been replaced.

Contractor's Assistant: Do you plan on doing the work yourself?

Right now yes.

Contractor's Assistant: Anything else we should know to help you best?

I think that's all the info I can provide
