Are outside fans operating? It's an audible whirr or buzz from upper grill. Elec and gas sources the same result? Extreme test- you can connect a/c power direct heater in stack. This will operate cooling system direct full output without controls. Be sure to disconnect and secure existing leads at the heater with shore power disconnected. Check stack uptake thermo trip first. Can open on over temp of gas firing.
Anyway if it cools this way the cooling unit is fine, problem is in controls.
