The Bosch 3D90-3B may be the best gas furnace on the market but the problem with it is that it has a few errors.

Some of these are Error 90, Error 91, Error 92, and Error 93.

The furnace error 90 is a result of the combustion sensor being out of calibration.

When you get an error 90, it might be due to a blockage in the furnace.

You can check for blockages by removing the fuses, after which the temperature should decrease. The fuses are located in a fuse box or breaker panel. If it doesn’t work, please contact Bosch customer service.

The most common error on Bosch Furnaces is Error Code 90. This error is typically caused by the blower fan motor failure, which will cause the furnace to shut off, leading to a lack of airflow.
