If you've plugged in your GHDs, switched them on, and been met with a constant beeping and cold plates — don't panic, and please don't bin them yet. In cold weather, this often isn't a fault at all. It's a safety feature doing exactly what it's designed to do, and you can usually fix it yourself in a few minutes without spending a penny.
I've been repairing electronics for over 25 years, and a straightener that seems broken in cold weather can turn out to be fine. So before you book anything, let's check whether yours is one of them.
The beeping is probably "shiver mode"
Every GHD model made after the old 3.1b — so the 4.0, 4.2b, 5.0, Gold, Max, Platinum+ and the rest — has a built-in cold-protection feature that many people have never heard of. If the straighteners drop below roughly 11°C, they refuse to heat up and instead sit there beeping continuously.
It's often nicknamed "shiver mode", and it's completely deliberate. Here's why it exists: if a very cold pair of straighteners suddenly heated up, condensation could form on the electronics inside — the same way a cold window mists up when warm air hits it. That moisture on the circuit board can cause real, permanent damage. So GHD designed the irons to simply wait until they're warm enough to heat safely.
The catch is that GHD never really explained this to anyone, so the symptom — beeping, no heat — looks identical to a serious fault. It isn't.
When shiver mode is the likely culprit
You're probably looking at shiver mode, not a fault, if:
It's cold weather, or the straighteners have been somewhere chilly — a bathroom, a car, a bag left overnight, a house where the heating's been off.
The beeping is constant, and there's no heat at all from either plate.
The straighteners worked perfectly the last time you used them in a warm room.
If that sounds like your situation, the fix is simple.
How to fix it (for free)
All you need to do is get the straighteners back up to normal room temperature — above that ~11°C threshold — and they should behave completely normally again.
Bring them into a warm room and give them 20–30 minutes to warm through naturally. This is the safest option and usually all it takes.
In a hurry? Rest them on (not touching) a warm radiator for a little while, or gently warm them with a hairdryer on a low setting for a minute or two. Don't overdo it — you're just taking the chill off, not cooking them.
Once they're up to temperature, switch them on again. If the beeping stops and they heat as normal, that was shiver mode — nothing was ever wrong, and you're good to go.
A quick reassurance: letting them warm up and trying again causes no harm whatsoever. It's always worth ruling this out first, because it costs you nothing and saves you sending in a perfectly healthy pair of straighteners.
When it genuinely is a fault
If you've warmed the straighteners thoroughly, tried them in a warm room, and they still beep or still won't heat — then yes, at that point you're likely looking at a genuine fault. The good news is that these are almost always repairable, and usually for far less than the cost of a new pair.
The most common causes of a GHD that powers on but won't heat are:
A blown thermal fuse — a small safety component that fails with age and is the single most common GHD fault there is. It's an inexpensive part and a straightforward fix.
A failed heater element — often showing up as one plate heating and the other staying cold.
R8/R11 resistors on Mk4 and Mk5 models — a very common weak point that I replace as a preventative on every repair so the same fault can't simply come back.
Working out which one it is means opening the straighteners up and testing the components properly — which is exactly what I do. I fix all of these at my own bench, in-house, and every repair is heat-tested to make sure the plates reach the correct temperature and PAT safety-tested before it comes back to you.
What it costs, and my promise to you
I repair "won't heat up" faults for a flat £29 all-in for standard models (£39 for Gold, Max and Platinum+), and that includes parts, labour, return postage and the safety test — no hidden charges and no "we'll tell you the price once we've got them" games.
Every repair is backed by my no-fix-no-fee promise and a 12-month warranty against the same fault returning. If I can't fix it, you don't pay for the repair. And if it turns out it was only shiver mode after all, I'll always tell you straight.
If you've ruled out the cold-weather cause and your straighteners still won't heat, you can book a GHD not heating repair here — it takes a couple of minutes, and I'll send you simple instructions for posting them in.
Not sure which GHD model you've got? It matters for the price and whether it can be repaired at all — here's how to find your GHD model number.
