I have a Bosch condenser dryer that heats up and after 3-5 mins cuts out (no lights/power). After is cools a while, the machine can be restarted and runs a while longer until it shuts down again. This process repeats several times, with each progressive drying cycle being a little longer than the previous until the clothes are eventually dry.I've tested the the thermal-protector for continuity and the NTC-sensor on the heating element appears to be fine (tested for resistance). Could it be a faulty sensor/component on the control board that's getting too hot and cutting out the power? And if so, can it be easily identified/replaced, or would I need to replace the whole control board?Any help would be greatly appreciated!
If I could give them 10 stars I would. Don is extremely knowledgeable but more importantly honest. PSE had done a free diagnosis and told me I would need a new induction motor for around $850 or possibly a new furnace. PSE doesn't do the repairs so I found Affordable furnace on yelp. Don showed me where the noise was coming from and that we didn't need the other repair. He performed some routine maintenance and enlightened me on much better furnace filters. He said we will probably need a new furnace in a couple years but given the fact we've lived here 18 years and it was here before we got here I think we're doing pretty good. When it is time for a new furnace there's only one company we will be calling. Thanks Affordable Furnace!
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
