I am trying to help my mom fix her heat at her mobile home. She has an Intertherm FEH-015HA furnace. Symptoms are:

- blower motor/fan not working. Will not come on at all either when turning thermostat to "on" or "auto". Even though no warm was being blown out, temperature reading on thermostat kept rising?

- Furnace cannot be turned off via thermostat. It will only turn off if we flip the breaker. Will not turn off by setting thermostat to "off" or by adjusting temperature

- When she first noticed the issue she said the air around the furnace was really hot?

She literally just had a technician out who replaced a fuse or two and it seemed to work great for a few days until it started doing the above. Any help is appreciated as it is very expensive to keep having techs come out. Thank you in advance!!
