I have a Frigidaire Dual Stage 96% efficient furnace. Wild return without installed return ducts and we have been having and issues recently.
Combustion fan starts up on high, Burners Light, Blower Turns on, 10 seconds combustion fan slows and that is when gas cuts off.
Tries to start the process again except now the pressure switch on the condensate side clicks. Burners have trouble lighting as gas is cutting on and off. Works after 30-60 minutes. If I pinch the hose for that pressure switch it starts right away.
IWe have tested everything and can not figure out the issue and looking for any help.
