LG (GR-B207GUQA) reculatant to go below zero in the freezer, fridge temp is fine, not something i know about so thats why im asking… dose it need a re-gas as its very slow to drop temperature. its zero in the freezer at the moment 22.00 and i recon its going to take till morning to get anywere near safe for food if ever. turned on at 12 mid day. Many thanks 🙂
How old is it?
A refrigerant system is sealed, if it’s gonna loose gas it’ll do so pretty quickly after installation. If it’s a couple of years or more old then I’d be looking elsewhere for the problem.

Re: possiable re-gas needed
Hi K, thanks for the reply, its just three years old, there was a crack in the freezer wall that ive just covered with silver heat resistant tape to see if it helps, its now droped to -3 from zero in one and a half hours and still droping. If as you say its not a gas problem can you make a guess as to where i need to be looking. Thanks again K. 🙂
My guess would be a weak compressor if it’s running all the time but I’m not familiar with LG machines enough to know if there’s anything you should be looking for.

Re: possiable re-gas needed
Mmmm that sounds like the most expensive part to me, was hoping if it wasnt a gas problem it was going to be The thermostat. and i would think its an electronic type and not a manual one.
It is possibly a thermostat or thermistor failure, but it wouldn’t be my first port of call with the symptoms described. 😕

the compressor part number is LA95LAEM 1PH made by LG. Just about to price one up.
😥 calnt find one anywere
Re: possiable re-gas needed
Are the fan Motors operating
Ie Fan motor at Evaporator & Condenser fan motorRe: possiable re-gas needed
Yes the fan is running and the fans that blow cold air into the appliance come on a few seconds after the doors are closed, the temperature is now -12 in the freezer and 3c in the fridge. Im using a small plastic gauge that has fridge temp in a blue area then freezer temp in a blue area with marked out bars in between showing 2c incriments.
I removed the rear cover yesterday and there was a large amount of fluff and dust around the condenser and its fan, this is now all removed. the compressor (part No LA95LAEM) was running and no hotter than i would expect (borderline to be able to touch and hold). If its a new compressor and a re-gas what kind of price am i looking at?. Thanks again. 🙂
UPDATE the freezer temps just gone back up to zero from -12 in about 1hr. could this be the thermal cutout on the compressor as its working overtime ?,
Re: possiable re-gas needed
Hi yes its a frost free freezer. it now drops to -18c then gose back up to 0c and keeps doing this. but just latly it now gose up to 4c same temperature as the fridge. here are some photos of the rear of the applaince it was running at the time of the photos. Ps the dust has been removed now. still no difference.

Although that condenser needs cleaning it’s not bad enough to be causing the symptoms you’ve got. You need to establish first whether it’s a defrosting problem or a thermostatic control problem. It’s obviously not a refrigeration system problem [ie compressor or gas leak] if the freezer’s getting down to -18C and the fridge to 3C.
I’m not familiar with that model but I think you need to take the freezer evaporator cover off and inspect the evaporator to see if ice is building up on it, thus blocking the air circulation around the freezer. If it is [although I suspect it isn’t as the temp is varying wildly] you have to find whether it’s the heater, or a defrost thermostat or thermistor, or the pcb [or mechanical timer if it’s not electronic] causing it not to defrost.
If the evaporator isn’t iced up I think you’ve got a temperature control problem; evaporator thermistor or pcb not switching the compressor back on, or indeed whether it’s sticking on defrost, and thus rapidly getting up to 4degrees in the freezer.
Faults on this sort of fridge freezer can be difficult to diagnose even when you’re used to them. If you’re not sometimes you have to spend a lot of time finding your way around them, but sometimes it’s best to walk away.
If we’re lucky perhaps someone familiar with the model will pick up on the thread.

Re: possiable re-gas needed
Thank you Geoff, ive removed the cover and there is a build up of ice as you can see with this set of photos, down at tbe bottom the heater is free of ice as was 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the evaporator it was just the top bend that has a build up of ice, after defrosting you can see better whats there. Thanks Ps… photo 2093 was taken with the appliance on for about 1 min you can see the start of ice bulding up on the in pipe. PPs… Just looking at the cover ive removed there’s a definite amount of heat damage to the plastic, could this be normal for a defrost heater to damage the cover?

No, a defrost heater shouldn’t damage the cover, unless that particular model is prone to that. Perhaps it has stuck on defrost.
Partial build-up of ice at the beginning of the evaporator like that, with the rest of it clear would indicate a shortage of refrigerant, but in that case the temperature wouldn’t get down to -18. I think you need to test the refrigeration system first, but am wondering if there are are two faults on this machine. I don’t think I can help you any further.Bryan r600a is usually pretty good on long-distance diagnosis of this sort of problem; where is he when we need him?
Re: possiable re-gas needed
Thank you ever so much, you have helped me a lot, im lost with fridge/freezers. ill see if i can track Bryan r600a down. Also just to add to the problem i covered all the cracks in the plastic casing at the back of the freezer put it all back togeather and now it wont go below
+15 a good friend of mine dose aircon in cars etc, wonder if he might be able to regas me at a good price just to see if that cures it.
