If the blower motor runs all the time, there are three common issues: The fan switch on the thermostat is set to “on” rather than “auto” Relays in the control board are stuck in the closed position, so the blower is getting a constant supply of electricity, and the control board ...
A supplemental circuit board is provided for a furnace and air conditioning system to power the blower motor so that there is normal heat speed during a heat cycle, and normal, full speed when there is a normal cooling cycle. When there is a call for economy, dehumidification, or partial ...
To make the system work, you set the thermostat higher than the RV’s current inside air temperature, which triggers the furnace to activate the blower motor. Ultimately, if the system functions correctly, the propane ignites, creating hot air that’s distributed throughout the RV through the...

Blower motor: This component circulates the heated air through the ductwork and vents, distributing it throughout the home. Thermostat: The thermostat regulates the furnace’s operation, turning it on and off based on the desired temperature settings. ...
To prevent problems in the future, it's a good idea tohave the furnace tuned uponce a year to make sure everything — particularly the flame sensor — is in good working order. The sensor is much easier to clean when it has only a thin coating of carbon deposits than when it has a...
From Will's consulting I now understand that the Old furnace had been too large to allow temperature balancing, and was unable to draw enough air, causing motor-stress and the multiple blower-motor failures over the 16-years. Larry and Dalton did a great job installing the furnace, removing...
.Anytime you have furnace problems, your first step should be to check the thermostat. Ensure it is set higher than room temperature and set to “heat.” Turn the fan switch to on. If the fan doesn’t turn on, it’s possible the furnace isn’t getting power, or the motor is ...
with any type of furnace. Fresh air is connected more than 1 meter from the drop of the return air for the furnace then connected outside. If the fresh air is connected closer to the drop than 1 meter it will cause cold air to be brought into the room even without blower motor ...
But the truth is, even the best Carrier gas furnaces don’t last forever. The longer you stay in your home – and the older your heating system gets – the likelihood that you'll be paying for a gas furnace replacement or repair will increase. Common furnace problems you may experience ...
