What is model on heater?

Ask Your Own HVAC Question
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

On most of these Lennox units, the slow flash means we have power but thermostat is not calling for heat. Try connecting the thermostat wires from heater together and see if it will come on.We will go from here.

I've connected the wires from the heater and it does come on.
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

OK problem is in thermostat then. Tell me model on thermostat and how you have it wired.

Ok if you touch this R and W at thermostat and heater will come on but not when wires are connected and calling for heat on thermostat, the thermostat is defective.

Did you connect the wires here or at heater? You may have a break in wire in between

I disconnected the wires from the thermo and connected them.
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

That is what I thought. That tells us thermostat must be the issue .

Customer reply replied 1 year ago
I just bought it. I'll replace tomorrow. Will there be any damage to heater if we leave the wires connected.
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

Do you have the fan switch on thermo in AUTO position?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
It's in the on position
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

That is a universal thermostat that can be used with a normal central system I have seen it cause an issue . Just for fun lets put fan in Auto and see if it makes a difference. Really should not since we don't have a wire connected to G but I have seen it do so.

No different unit still comes on.
HVAC Technician: airheatman, HVAC Technician replied 1 year ago

I meant reconnect wires to thermostat and see if we could thermostat to bring it on.

Customer reply replied 1 year ago
Ha ha when connecting the wires to thermo I discovered I did not remove a protective cover. Once I removed this it worked like it should. Thank you for your time.
