H0530028412 Genuine Wok Burner Thermocouple for Haier Gas Cooktops and Cookers, Flame Failure Safety Sensor

H0530028412 is the genuine Haier thermocouple for the wok burner on Haier gas cooking appliances. The other burners use a different thermocouple, so make sure it's the wok that's playing up. There's no model list on file for it. Compare the number on your old thermocouple, or send the model number of your cooktop or cooker through the parts enquiry form before you order.

Wok burner lights then goes out? It's often the thermocouple

A thermocouple is the flame failure safety device on a gas burner. Its tip sits in the flame, and the heat makes a tiny voltage that holds the gas valve open. If the flame goes out, the tip cools, the voltage drops and the gas shuts off. When the thermocouple wears out, the burner lights while you hold the knob in but goes out as soon as you let go, or drops out part way through cooking. A dirty or bent tip can do the same, so clean it and check its position first.

Gas safety when replacing a thermocouple

This is a gas safety part, so the job belongs with a licensed gas fitter. Turn off the gas supply and isolate power to the ignition before work starts. The fitter will route the lead the same way as the original, tighten the valve connection to spec, leak test the joints and confirm the burner holds its flame.

Questions about this part

Can I fit a thermocouple from another burner?

No. The wok thermocouple is listed separately from the standard burner one, and length and fittings can differ. Use the number that matches your wok burner, and have a licensed gas fitter install it.
