Gestetner SP3200SF Open Heat Error Message G960-1600, G9601600
Below you will find repair advice for the Gestetner SP3200SF Open Heat Error Message. One of the main cause of this fuser error in these machines is either one of the thermostats has opened or the electrodes have gotten corroded and need cleaned. Below is some tips on how to resolve this problem. However, if you feel this repair is beyond your expertise or doesn’t fix your problem then I have provided links to order in a replacement fuser and at the bottom of the article you will find a link to the simple replacement instructions.
Gestetner SP3200SF Open Heat Error Message Repair Advice
1. In the first picture above you can see where the thermostats are located. When the machine over heats these thermostats open to cut off AC power to the unit. When the machine cools down, sometimes these thermostats close and other times they might stay open. When they stay open no AC goes through the circuit and you get the open heat message. In order to clear the message you probably will have to remove the fusing assembly and manually reset the thermostats.
2. Once you have the fusing assembly out. You will need to use a volt meter and check continuity across the thermostats. If you have continuity across the thermostats then check the lamp and electrodes, (Step 3). If you have no continuity across the thermostats then try them individually. Once you find the one that is open, turn it over so the side facing the hot roller is up. Typically this side as a black leaf spring on it. If you depress the leaf it will bend in. Take a can of air and hold it upside down and give the leaf spring an extreme cold shot of air. This procedure will close the thermostat back up. Test for continuity across the thermostat again. If it test good then install back in the machine and turn back on.

Note: This takes a good brand of canned air or a fresh can. Stoner Canned air works the best.
3. In the next two pictures you see the electrodes. Overtime these electrodes get corrosion on them that can lead to current issues. If the thermostats test good then I would look here. If they have lots of corrosion then take an emery board and file them down a little to expose fresh metal. You might have to also do this to the lamp or heating element also.
There you have it. If you have a little technical skill this job shouldn’t be to hard to figure out. Now if you’ve read this and are like, I ain’t doing that, then click on the link below for the fuser replacement instructions. I would point out that while I know this fix works and I’ve had many people read other articles and get their machines working, manufactures tend to shy away from this repair and recommend either replacing the thermostats or fuser. Given the age of these machines it might not be a bad idea to just replace the fuser. I’ve been running into issues where these fusers are starting to turn hard and cause jamming and motor locks.
