What is the typical resistance range for a normal hot surface igniter?

The typical resistance range for a normal hot surface igniter is between 45 to 400 ohms. This range is essential because it reflects the necessary electrical resistance needed for the igniter to heat up adequately for gas combustion in appliances such as ovens and furnaces.

A resistance value at the lower end of this range indicates that the igniter is in good working condition and able to conduct electricity effectively. If the resistance is too low or too high outside this range, it may indicate a malfunction in the igniter, affecting its ability to ignite the gas properly.

Understanding this resistance range is crucial during troubleshooting, as it helps technicians determine whether the hot surface igniter needs replacement or if other issues within the system need to be investigated. This knowledge is applicable not just in test scenarios but also in real-world maintenance and repair situations.
