Dispatched our Altadena, CA, A/C technician to a customer reporting issues with their heater. Upon arrival, our tech determined that the flame sensor had failed on the Day & Night unit. He was able to sand down the rust and reinstalled the sensor to provide temporary heating. Will need to order a new sensor and install it.
