Not very reliable

Had this Modine unit for 3 months now in a garage. It has been broken longer than it has been working. The inducer bearing went out after 1 week of usage. 3 weeks later a new inducer arrived and was installed. Worked for 1 week, then unit began to drip condensate from the unit. The drain was not plugged, an internal seal failed. While awaiting that to be fixed, after another few days, the unit kept turning on and off without providing any heat. It appears the sensor for exhaust airflow has failed. 2 weeks+ later, we are still awaiting the replacement parts to arrive. Total, out of 3 months, unit has only been functional for 2.5 weeks.
