Hello, locate, remove and clean the flow sensor...while you are at it get the part number or brand and model number of the flow sensor so that I can pull the manual on it,

The problem could be in the flow sensor itself, or the printed circuit board it sends its signal to, or in the pumped water loop, for instance a clogged strainer, or a design bug where some of the zones if it has any, are cycled off and there is not enough open flow to operate the sensor. (improperly designed or adjusted bypass loop)

Carrier has used various brands and types of sensors over the years.

Take a close up, exceedingly well focused photo of the carrier units wiring diagram and attach it here using the 'add files' link next to your send button.

We can go from there.

OPENING STATEMENTS

.

All I ask is please respect me and my input by selecting the***RATING LINK***at the top of your page, that is the only way I am credited through the site. Rating does not affect your charges nor ability to refund if not satisfied.

.

If you need to be coached through a full diagnosis/repair,and wiring etc. for up to two days, and wish to be trained to use test instruments...... that goes well beyond' Just a simple Answer' of course, and goes beyond what most other experts here offer.....rate my answer so far positively.. . and I will deliver that training and coaching to you All on the same dime so to speak.
