Heat Pump Not Working
The furnace runs blowing cold air and the heat pump won’t start. Check the Air Filter and make sure it is not dirty. If it is dirty remove the filter and turn the thermostat off and wait for 10 minutes. While you are waiting the 10 minutes, go through the home and open all the supply registers. Turn the thermostat on to heat and wait for up to 5 minutes. If the heat pump won’t start- CALL FOR SERVICE.
Turn the thermostat to EM Heat to temporarily get the Heat On. Then Call For Service.
Check the Electric circuit Breaker Panel. Look at the Circuit Breaker Marked HEAT PUMP and make sure it is on. If it is off try to reset the circuit breaker.
If it will not reset after 1 try - CALL FOR SERVICE.
If You Smell Gas !
Don't take this one lightly
PROPANE: Go to the propane tank and turn the gas off.
Normally there is a shut off valve on the tank top, maybe under the lift up cover on the tank. This often looks like a water faucet valve, close it all the way.
NATURAL GAS: There is a shut off valve at the gas meter. Shut the valve off.
In either case this one is not to be taken lightly - Call Marshall's for service to resolve the underlying problem
Gas Furnace - Not Working
The furnace runs and blows cold air. Check the Air Filter and make sure it is not dirty. IF it is dirty, remove the filter and turn off the power for the furnace at the Circuit Breaker Panel or at the on off switch at the furnace (if it has an on off switch) and turn it back on. Also make sure all the supply registers in the home are open and not blocked. Make sure the individual supply filters that can be purchased and installed in each of the floor registers are removed. If this does not work to get the furnace started-CALL FOR SERVICE.
Digital Thermostat Blank- Try replacing the batteries. Some thermostats rely on battery power for full operation.
If replacing the batteries does not solve the problem, go to the electric circuit breaker panel and check the circuit breaker marked –FURNACE. Make sure it is on. If it is off, try to turn it on. If it cannot be turned on in one try-CALL FOR SERVICE.
IF you have a Propane Furnace and the furnace will not start, check the fuel level at the tank. There is a gauge at the tank, normally on the tank top under the lift up cover. Look to make sure the level is above 15% to 20%. If the level is lower than this Call the Propane Company and request a fill.
