Hi all! I'm house sitting and had to call the HVAC guys when the furnace wouldn't fire up this morning. Trane TUX100R948W
Ignitor and 5 burners were replaced and now it runs fine. Tech noted that: "looks like the secondary heat exchanger is leaking condensation. Unit is getting rusty on face plate and in L channel across bottom of face plate."
So, before I have them replace the secondary heat exch. I want to make sure he's not just trying to upsell me. But he warned that if left as is it could leak condensate onto the circuit board and end up costing more money.
This furnace sat idle for 2 years without running at all before I arrived in Feb. The basement is sand floor and block wall. We are in NW Michigan where winters are brutal with much lake effect snow. When I asked the tech if this could have contributed to the condition of the furnace/heat exch. he seemed skeptical. He thought it was more likely a design flaw in the heat exch itself (something about cheap plastic screws).
I don't want to DIY. I like the guy and will have him back out to do the additional work if it is needed.
What do you think? And thanks in advance. What a cool forum
