E3 code diesel heater, how to check the glow plug with a multimeter

If you’re having issues with your Chinese diesel heater and you want to see if your glow plug is faulty then you can do so with a multi meter.

Select ohms on the multimeter and set it to 200 to test the glow plug, make sure you check the voltage on your leisure batteries as well Incase you’re below 12.5v, sometimes low voltage can cause an E3 code. Let me know how you fixed your E3 code!

Finally a 2 minute youtube that gets right to the point without all the bollocks -- thank you. I don't entirely understand the numbers and what they mean since I'm no good with electronics. Often my heater starts for a minute, I might hear a few clicks from the fuel pump but then shuts down with and E-01 error. Sometimes it completes startup, after which it will run all night. I replaced my solar-charged battery. I'm not sure, but I suspect it completes startup and works only if my battery is at full charge after some time in the sun; if it's at all depleted, heater startup won't complete. Please provide more details on how I might diagnose, and whether glow plug or fan are among the suspects. Thanks again!

The glow plug is a resistor. It is not polarity sensitive. So it does not matter what lead goes on what wire. 😊

I have a Early Heater 2kw, small display with single rotary Dial. Message said Ignition Failure. Old glow plug showed 1 on meter no zeros. New Glow Plug showed 0.06 . Put new one in and all working. same meter. All Good. Cheers.

hello
I changed the glow plug
Battery with 12.8 voltage
I even changed the main board
The fuel line and pump are also healthy
But it still gives error e03

Hey maybe you might be able to help. Just installed brand new heater like yours tested like you did except mine reads .3 .4. I stuck my finger in the hole to touch glow plug and it was hot. The display read 13v but still throwing a e3 code.

Really enjoyed your wood stove video and subscribed!!! I'm going to be doing my own van conversion in the next few months and wanted to ask you would you recommend getting a diesel heater if you also install a wood stove burner. Many thanks,

Rory

Hey I have a heater reading e 3 glow plug reading 5.7 ohms, what should it be? Heater is only a few weeks old, ran great, after about 5 times of using it now reads e-3, from your experience is there something else I should check
