Hello Pearl -
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.

Customer: Thats all the info (7 flashes)
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the HVAC Technician about your situation and connect you two.

Hello, I will assist you with that.Can you provide me with the exact model number located inside furnace on a rating plate sticker.
Expert:  Gaztech replied 8 months ago.
That means the high temp. safety has opened to shut down the burners. Most likely causes, is a dirty air filter, closed feed and/ or return vents, as well, clogged blower wheel or a dirty air conditioning coil located above furnace in the plenum duct.

Does the main blower go on after it locks out?
Expert:  BillyHvac replied 8 months ago.
Hello, your main issue is the limit is still open...it is not relevant if the main blower goes on after it locks out...because you are already locked out.If you would like to know how to reset or repair let me know. My name is***** will get it going then address why.
