Step 1 – Inspection of the heater power switch and the breaker

- Check if your thermostat is working correctly by changing the power settings.
- Contact your Ecobee Expert if the problem persists. We do not want any wrong steps that may create an additional issue.
Step 2 – Overheated or Tripped Heater
- It is known that every heater has a sensor that senses overheating and trips. This inbuilt sensor saves the heater from malfunctioning. However, it trips when the settings you process are not functional. For example, the fan may have stopped or would have started cooling the whole device. There are couple of reasons why your heater can overheat. These reasons are:
- If the temperature outside is relatively low.
- If the filter is filled with dirt or clogged.
Step 3 – Furnace Fuse
The fuse saves the furnace from the power surges. If you want to check, if it is faulty. Follow the steps below:
Note – Turn off the whole device. Ensure before beginning to avoid any shocks.
- Open the furnace panel to review the fuse.
- When this is not the problem, check the wires.
- If you see the fuse in black color, there is a chance it has blown. Blown-out fuse is causing the problem.
- Check for the Amp of the fuse. It should be either 3AMP or 5AMP (not interchangeable).
- Go ahead and replace if you find anything faulty.
Step 4 – Condensate Drippage is an issue.
Is water building up in your thermostat? This issue can make your screen go blank. Water exceeding a specific limit will switch your thermostat off.
Avoid this clogging by running through the checklist below:
- Is there any type of leakage or moisture in or around?
- Is the drain pan getting dull?
- Is the drain pan overflowing?
- Is there a problem with frequent restarting?
- Any water damage near the condensate?
Do not worry; you can resolve these issues. Find the guide below and follow these steps.
- First, look for the drainage pan; it will be on the sides of the device. Some devices will be behind the whole machine structure.
- Clean the pan if you find it full. Ensure that this step is taken carefully.
- While you are cleaning the pan, look for clogging in drainage. You can hire an expert if you do not wish to continue further.
- Turn on the float switch which got turned off because of debris.
Remove the safety panel if you face a problem identifying the float switch. Look for terminal R and follow the wire. The switch it connects to is your float switch.
B.The Ecobee thermostat is newly installed on
There are chances that these fixes will not work for you. This issue mainly occurs when your Ecobee thermostat has been recently installed. However, here’s what you can do.
Step 1 – Start by checking the power wire.

Step 2 – The C wire
There should be an extra C wire with the device. Ensure to replace these wires as soon as there is a need. Connect the C wire for the thermostat to start working.
Step 3 – Power Extender Kit
Ecobee 3 and 4 are required to consider the following things while wiring:
- The wire R goes to the R Terminal
- The wires G goes to the C Terminal
- Wire W goes to the W1 Terminal
- and wire Y goes to the PEK Terminal
Step 4 – Check the placement of the device on the backplate
Displacement is often responsible for hindrance in the whole functioning of the thermostat.
