A blown furnace fuse can cause major failures for your HVAC system and therefore cannot be ignored. A blown fuse can be caused by the overheating of appliances, and to prevent such heating, always be in contact with heating services near me.
A Furnace Fuse is a piece of equipment that preserves electrical appliances from short circuits, making it an important tool for all heavy appliances and requires a periodic check.
Reasons for Blowing of Furnace Fuse
1. Defective Electrification
Wires that are old, of least quality, or badly connected are a threat to the life of the appliance as well as people near to that appliance. Electrification of wires is important, and the task needs to be performed carefully by a professional heating repair near me.
2. Inefficient Maintenance
HVAC appliances, once installed, need periodic maintenance to work efficiently and effectively. Lacking to which the major problem that occurs is dust accumulation on air filters which may head towards overheating and failure of the fuse.
Understand Fuse Blowing Concept
Furnaces need electricity to run. The fuses on the furnace are of low voltage (3 to 5 amps). When it is overloaded than the limit, the fuse blows and prevents the energy from flowing further through the wires of an appliance.
For illustration, it happens at the time of hot summers when AC tries to match the temperature and provide a better cooling effect, to which it requires more heat energy than the capacity of the fuse, which conclusively results in a blow of fuse.
Check Fuse Blown
When a furnace fuse blows, your HVAC unit may not get the electricity that it needs. The foremost sign of a fuse blown is that your AC switches off on its own with a bit of humming noise. Now to check whether it requires heating repair services or not, follow few simple steps-
- Disconnect from the main electricity meter board.
- Unfold coverings outdoors as well as inner in the meter board vigilantly, which will assist in exposing the live wires, need to be cautious while performing this step.
- Turn the voltmeter to 0 or infinity.
- Record the reading on the voltmeter. For this, you’ll find 2 sets of wires, i.e., line wires denoting incoming flow and load wires denoting outgoing flow. It should be approximately 200 to 220 volts. Inspect both incoming and outgoing readings. If this is the reading, it ensures the fuse is not blown, and there may be some other problem related to your unit.
- If the voltage is not this, the fuse is blown, and the last step includes cautiously replacing the fuse and searching for heating repair services near me.
