Re: SS 5.O problems after thermal fuse replaced

Hi Canales,

A reasonable amount of wobble is normal, however the cable socket should deal with that an maintain a good connection. The socket is definitely not a precision piece of engineering!

Re: info MK5 value of resistor

Hi, Have you looked at our repair guide? There are not many things that go wrong with these GHDs, so it is likely a "standard" fault. See https://www.ghd-repair.co.uk/guides/mk4_debug.html Then post the resistances of the following: - Heaters when connected - Heaters when disconnected - R8...

Re: 5.0 GHD Repair issue

Disconnect the heaters and measure the resistance of each heater in isolation

Re: 5.0 GHD Repair issue

Then one of the elements is open circuit and needs replacing.

Re: 5.0 GHD Repair issue

No polarity does not matter. When both heaters are connected you should measure 35 ohms as they are wired in parallel. Do you get 35ohms when both connected?

Re: 5.0 GHD Repair issue

As long as it is ok for over 200degC, then it should be ok. Use sparingly!

Re: 5.0 GHD Repair issue

Hi,

Sounds like you need a new heater with thermistor on the non switch side. Do you get 35 ohms or 70ohms when you measure the heaters with them both connected?

Regards,

Re: No LED No heat, looks dead

If the thermistor is detached then the temperature control does not work so the switch side heater element overheats and blows the thermal fuse.

Re: No LED No heat, looks dead

You will need to take the back off the heater and see if you can see the thermistor.

May also be worth just sending them off for repair as if you need a new heater with thermistor and a thermal fuse it won't be much more expensive. See http://ghd.repair/service.

Re: No LED No heat, looks dead

Looks like the thermal fuse has tripped. Is the thermistor securely attached on the non switch side?
