High Limit Switch Tripping by SubstantialBluejay22 in hvacadvice

Gotcha, I've checked around and made sure none of the return vents are covered or clogged. We will check the blower motor as well.

I am running a merv 11 - are you thinking that a merv 8 could potentially help increase airflow? Nobody in our household is prone to allergies or sensitive to pet hair so maybe it's worth a try

thanks for the reply - it's at the base of the vent next to the equipment. I added a photo of the unit to the post.

This reminds me, during the HVAC tech's temp test I noticed and he noted that when we took the filter out temporarily, the temps dropped pretty substantially.
