HONEYWELL THERMOSTAT NOT TURNING ON HEAT? (Try these Repair Tips)
If you have set your thermostat on HEAT mode for quite some time, but it wonβt warm up the room, there must be some issues. Unresponsive heating systems can be painful when itβs too cold. There can be many causes for a Honeywell heating not working. You need to figure out the problem and then use the solution to fix the heating issue. In this article, we will provide you with some repair tips that you can use to fix the no-heat issues.
1. CHECKING THE WIRES:
Wiring your thermostat is one thing, and the presence of faulty wires is another. The first tip is to remove the thermostat case and check if the wiring is loose or connected to the wrong terminals. This can be a significant cause if the thermostat is not heating your room, even if it has new batteries. Rewire your thermostat before it damages your device.
Use safe tools to fix the loose wires. Connect the cables to their respective terminals by matching the letters on the wires and terminals. Attach the case back again into the thermostat. I hope now your thermostat is heating the room properly.
2. TEMPERATURE MIGHT BE SET TOO LOW:
Is your thermostat not reaching the set temperature? Another reason for a faulty heating system can be the thermostat temperature set too low. The room temperature must be the same as the temperature set on the thermostat for the heat to work.
For example, If your room temperature is set to 60 degrees, the thermostatβs temperate should also be 60 degrees. If both match, this is when your thermostat will start to draw the heat. If your room temperature is low, then the temperature is set. Check the thermostatβs temperature now.
3. REPLACING THE OLD BATTERIES WITH NEW ONES:
Any electrical appliance needs a suitable power supply to function correctly. Your Honeywell Thermostat heater not working requires a 24V power connection for a sound temperature control system. If you have been using the same battery for your Honeywell Thermostat for too long now, your thermostat will have issues, like its heating system will stop working. The batteries usually run out of energy due to circuit breaks or power outages, which can be alarming. If your thermostat has old and drained-out batteries present then itβs display can also go blank.
STEPS TO FOLLOW:
STEP 1 β You need to turn off your thermostat from the circuit breaker
STEP 2 β Then remove the old batteries from your thermostat
STEP 3 β Insert the new reliable batteries in your thermostat
STEP 4 β Turn on your thermostat from the circuit breaker
This will fix your Honeywell heat not working issue. Replacing batteries is an easy way to save money and time.
4. TURNING ON THE FURNACE:
Every thermostat draws out the heat from its furnace. You might think your furnace is ON but still not heating your room. It is because someone accidentally turned off the furnace. First of all, locate the circuit breaker in your thermostat device. If your thermostat is electrical, it will have a double-lever breaker; if it works with gas, it will likely have a single-lever breaker.
Identify the circuit breaker, and turn on the furnace if it is off. Close the furnace door again because it wonβt work if left open. Another reason can be a dirty flame sensor. If it is not cleaned, it will turn off the furnace. Clean your furnace flame sensor and tune it up for better results.
5. CHECKING THE CIRCUIT BREAKER:
So you have turned on your thermostat when the room is cold but it is still not heating; why? Check the circuit breakers. Your thermostat is ON, but the circuit break might have tripped. Go to the panel and check the circuit. If the breaker has tripped, switch off the system on the thermostat. Reset the breaker and then turn ON the power switch of the heating system.
6. CHECKING THE TEMPERATURE SENSORS:
Every thermostat has a temperature sensor to control the room temperature automatically. After measuring the room temperature, the sensor activates the cooling/heating depending on the calculated temperature. If your thermostat sensor is faulty, it will show different readings on the display screen.
To check whether the sensor is working or not, measure the room temperature and then see the reading on the screen. If both readings arenβt the same, your sensor is broken. Get a new temperature sensor for your Honeywell Thermostat. This will immediately fix the Honeywell heat wonβt turn on issue.
