Hello,

My name is Billy.

Quite often this is due to no power to the thermostat because of no power to furnace, blown fuse or tripped water safety.

Do you have access to the furnace?

thank you, ***** ***** has a circuit board that will have lights lit...can you remove the front door ?

HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

when front door off you will see a panel in bottom with a view port the size of a quarter...look in this window for any lights that are lit or blinking.

If you remove the panel with view port we can check the small breaker on side of control box.

ok , i do see the lights and i removed the panel with the view port. the lights shutt off as there is a switch that when panel is removed, the lights turn off. Beside this trip switch, ther is a small black switch with "3amp" written beside it
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

activate the 3 amp switch..it may or may not be tripped.

Then..the water switch...would you be able to bypass for a test? Basically remove the 2 wires that go to it and connect togther as though it wasnt there?

what should i expect to see or hear?
Customer reply replied 1 year ago
how do you activate the 3 amp switch?
Customer reply replied 1 year ago
is there any specific way to remove the wires from this 3 amp switch??
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

Power to the thermoststat should appear.

The 3 amp is just a little rocker switch..if it is tripped you will be able to press one side down and hear a click..if it is not tripped it will not move.

We are NOT bypassing the 3 amp.....we ar wanting to bypass the water safety switch.

Can you post pic of the drain or pump?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
where would i find the drain or pump? would it be in the same area as the circuit board or above it?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

attached to the furnace is an ac coil...from this comes a drain pipe that drains water/condensation....do you see this?

Ask Your Own HVAC Question
Customer reply replied 1 year ago

HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago
