Is the defrost cycle running nonstop, or never running at all? There\u2019s a good chance there\u2019s one single, small part causing the problem \u2013 the defrost thermostat, or bimetal thermostat.This component, found behind the back panel of your freezer compartment, measures the temperature of the evaporator coils and signals for them to shut off if they grow too warm. So, if it goes bad, the whole defrost assembly can run into issues, which will disrupt the temperature in both the freezer and fresh food compartments of your refrigerator.\r\n\r\nLuckily, this is a quick and easy fix. Swapping out the defrost thermostat yourself is much faster and cheaper than hiring a technician to come out for a professional repair.

Before you grab your wire cutters and start disassembling things, though, there are a few other symptoms you can watch out for.\r\n\r\nWhen the defrost thermostat in your refrigerator is bad:\r\n<ul>\r\n \t<li aria-level=\"1\">The evaporator either will not run or will not stop running. Listen to your refrigerator when you\u2019re in the kitchen. If it seems like your fridge is running a lot or never running, it could be that the thermostat has gone bad.<\/li>\r\n \t<li aria-level=\"1\">The fresh food and freezer compartments will be warmer than they should be, with the refrigerator being warmer than the freezer. The FDA recommends you keep the temperature in your fridge below 40\u00b0 F (4\u00b0 C), and your freezer at or below 0\u00b0 F (-18\u00b0 C).<\/li>\r\n<\/ul>\r\nTo test your defrost thermostat directly, you\u2019ll need that multimeter we mentioned and potentially a pair of wire cutters. Your refrigerator should also be cold when you test:\r\n<ol>\r\n \t<li aria-level=\"1\"><b>Unplug the refrigerator and gain access to the defrost thermostat. <\/b>You can use the instructions in our how-to video to reach the defrost thermostat.<b> <\/b><\/li>\r\n \t<li aria-level=\"1\"><b>Disconnect the thermostat.<\/b> You may be able to unplug the thermostat for this, but on some models of refrigerator, the thermostat\u2019s wires will need to be cut.<\/li>\r\n \t<li aria-level=\"1\"><b>While the refrigerator is cold, touch a multimeter probe to each terminal or wire.<\/b> If the thermostat has continuity, then it\u2019s not the issue. If it doesn\u2019t have continuity, then the part has failed and needs to be replaced.<\/li>\r\n \t<li aria-level=\"1\">If the thermostat is working, you can reconnect it with a pair of wire nuts or butt connectors. Need help diagnosing your problem? Check out <a href=\"https:\/\/www.appliancepartspros.com\/b\/refrigerator-or-freezer-thats-too-warm-top-6-reasons-and-fixes-with-video\/\">our guide<\/a> to diagnosing problems with a freezer that\u2019s too warm.<\/li>\r\n<\/ol>\r\n<h2>Finding The Right Replacement Part<\/h2>\r\nTo ensure you\u2019re getting a thermostat that\u2019s properly calibrated for your fridge, you should opt for a genuine manufacturer-made, or OEM, part. Luckily, finding one is as simple as typing in your refrigerator\u2019s model number on the <a href=\"https:\/\/www.appliancepartspros.com\/\">AppliancePartsPros.com<\/a> search bar! Once you\u2019ve placed your order, you\u2019ll have the part in just a couple of days.\r\n\r\nNeed help finding the model number? If you don\u2019t have access to your manual, you can find the number on a label on the refrigerator. Check the following spots:\r\n<ul>\r\n \t<li aria-level=\"1\">On the exterior door or sides of the appliance<\/li>\r\n \t<li aria-level=\"1\">Inside the door or on the door frame<\/li>\r\n \t<li aria-level=\"1\">On the interior ceiling of the freezer or refrigerator compartment<\/li>\r\n \t<li aria-level=\"1\">On the inside wall of either compartment<\/li>\r\n \t<li aria-level=\"1\">On the fridge floor, beneath the crisper drawers<\/li>\r\n \t<li aria-level=\"1\">Behind the kickplate at the bottom of the appliance<\/li>\r\n<\/ul>\r\n<h2>How To Replace A Defrost Thermostat<\/h2>\r\nFor our tutorial video, we completed this repair on a Whirlpool side-by-side refrigerator. Regardless of your refrigerator\u2019s brand or style, the defrost thermostat is going to be found clipped to the evaporator coils behind the back panel of your refrigerator\u2019s freezer compartment. While the steps to get behind that panel may be different from what we\u2019ve laid out here, replacing the thermostat itself is the same, so you may find this guide helpful even if you don\u2019t have the same brand or model of refrigerator.\r\n\r\nThat said, don\u2019t forget to check out <a href=\"http:\/\/www.youtube.com\/c\/AppliancePartsPros\/\">our YouTube channel<\/a>. We have tons of video guides for a variety of refrigerator brands and models. If something in this guide isn\u2019t lining up with your refrigerator, you may still be able to find assistance through one of our other videos!\r\n<h3>Tools for the job<\/h3>\r\nWhile you may not need all of these tools depending on your refrigerator\u2019s style, it\u2019ll still be handy to have the following tools ready before you start:\r\n<ul>\r\n \t<li aria-level=\"1\">Phillips & flathead screwdrivers<\/li>\r\n \t<li aria-level=\"1\">Wire cutter or crimper<\/li>\r\n \t<li aria-level=\"1\">Wire nuts or butt connectors; we used butt connectors in our tutorial video<\/li>\r\n \t<li aria-level=\"1\">Work gloves<\/li>\r\n<\/ul>\r\n<h3><span style=\"color: #ff0000;\">Before you begin\u2026<\/span><\/h3>\r\n<span style=\"color: #ff0000;\">For safety, be sure to disconnect your appliance from power either at the wall outlet or circuit breaker. Never do maintenance on an appliance that is receiving power! For this job, you may also want to temporarily shut off the water supply to the refrigerator, but it isn\u2019t necessary.<\/span>\r\n\r\nThe defrost thermostat is installed behind the back panel of your refrigerator\u2019s freezer compartment. To remove that panel and reach the component, there\u2019s some prep you\u2019ll need to do:\r\n<ul>\r\n \t<li aria-level=\"1\">Move any frozen food you have in the freezer to the refrigerator\u2019s fresh food compartment or a cooler.<\/li>\r\n \t<li aria-level=\"1\">Remove the ice bucket. You may need to press a release tab to get it out, but it should come away by hand.<\/li>\r\n \t<li aria-level=\"1\">Remove any bins and shelves. Shelves can usually be removed by lifting up before pulling them out. Bins are the opposite: pull them all the way out and then lift up to free them from their rails.<\/li>\r\n \t<li aria-level=\"1\">Remove the bin rails on the freezer walls. They can be removed with a Phillips screwdriver. The rails are likely different sizes, so keep track of which side you removed each rail from so that you\u2019ll install them on the correct side when you reassemble.<\/li>\r\n \t<li aria-level=\"1\">Remove the shelf mounting clips. How you remove these will depend on your refrigerator model. Try pressing up on them from the bottom, but if they don\u2019t slide up and release that way, don\u2019t force it. You could break them. Instead, consult your manual.\r\n<ul>\r\n \t<li aria-level=\"2\">On some refrigerators you can\u2019t take these clips out. That\u2019s okay! You\u2019ll just need to turn the panel and navigate it out of the freezer around them when you remove it.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<h3>Replacing a defrost thermostat<\/h3>\r\n<ol>\r\n \t<li aria-level=\"1\"><b>Remove the screws holding the back panel in place. <\/b>In our Whirlpool refrigerator, there were six Phillips screws total to remove.<\/li>\r\n \t<li aria-level=\"1\"><b>Remove the light cover toward the top of the freezer, under the ice maker. <\/b>If your refrigerator has this, it can be removed by squeezing it and releasing the locking tabs holding it in place.<\/li>\r\n \t<li aria-level=\"1\"><b>Remove the back panel <\/b>to gain access to the evaporator. Lift it up from the bottom. There are a couple of tabs near the top that you\u2019ll need to free the panel from. Once the panel is free of the top tabs, tilt it out slightly from the bottom. The top of the panel will still likely be seated behind the ice maker, just pull down slightly to free it. Once the panel is free of all tabs, it can be removed. You may have to rotate it out if you weren\u2019t able to remove the shelf tabs or bin rains.<\/li>\r\n \t<li aria-level=\"1\"><b>Locate the defrost thermostat. <\/b>It is usually clipped onto the evaporator, on the top or one of the sides.<\/li>\r\n \t<li aria-level=\"1\"><b>Carefully remove the defrost thermostat from the evaporator.<\/b> Any damage to the evaporator coils won\u2019t just be expensive to fix\u00a0 \u2013 it could potentially be dangerous.<\/li>\r\n \t<li aria-level=\"1\"><b>Using a wire crimper or wire cutters, cut the defrost thermostat\u2019s wires to remove it.<\/b><\/li>\r\n \t<li aria-level=\"1\"><b>Strip the ends of the wires still attached to the refrigerator. <\/b>You\u2019ll be connecting the new defrost thermostat to these.<\/li>\r\n \t<li aria-level=\"1\"><b>To prep the new defrost thermostat, strip the ends of its wires.<\/b><\/li>\r\n \t<li aria-level=\"1\"><b>Connect the new defrost thermostat to the refrigerator.<\/b> You can use either wire nuts or butt connectors. When using wire nuts, simply twist the wires together and cap each new connection with the nut. For the butt connector: Start by putting one butt connector on one of the defrost thermostat\u2019s wires and crimping it down. Now crimp the other butt connector down on the other wire. Attach each connector to the corresponding wire in the refrigerator and crimp them down.<\/li>\r\n \t<li aria-level=\"1\"><b>Reattach the new defrost thermostat<\/b> onto the evaporator coil in the same place the old one was clipped. Then push the wires up and out of the way.<\/li>\r\n \t<li aria-level=\"1\"><b>Reinstall the back panel.<\/b> You may need to press it or bend it slightly to get it seated properly. Use a flathead screwdriver to seat it beneath the ice maker properly.\u00a0 Make sure that it is resting on all tabs before reinstalling any mounting hardware.<\/li>\r\n \t<li aria-level=\"1\"><b>Reinstall the light cover.<\/b> It just snaps back into place.<\/li>\r\n \t<li aria-level=\"1\"><b>Reinstall the rails, wall clips, bins and shelving. <\/b>Make sure you put the rails on the correct sides. For the wall clips, the cups go in the back of the freezer and the pegs in the front.<\/li>\r\n \t<li aria-level=\"1\"><b>Reinstall the ice bin.<\/b> It should just slide back into place.<\/li>\r\n \t<li aria-level=\"1\"><b>Plug the refrigerator back in and turn the water supply on if you shut it off.<\/b> You\u2019re almost done! Since you did all that work with the door open, the freezer compartment has likely warmed up, so the fridge should kick on and start cooling immediately. Put your frozen food away, but keep an eye on things. Make sure that the temperatures in the refrigerator aren\u2019t climbing too high or dropping too low, and listen for the evaporator to make sure it\u2019s running and stopping properly.<\/li>\r\n<\/ol>\r\n<h2>Wrapping Up<\/h2>\r\nThe hardest part of this job is taking all that food out and then putting it back in at the end.
