The tube temperature sensor is on the wall of the coil inside the outdoor unit. The copper head is used to detect copper pipes, and the temperature conduction is fast; the rubber head is generally used to detect the ambient temperature, corrosion resistance, and high reliability. How to judge the resistance value of the air conditioner temperature sensor The following phenomena will occur if the air conditioner temperature sensor is broken, and the quality of the air conditioner temperature sensor can be judged by stopping: 1. The resistance value of the indoor ambient temperature sensor increases, causing the air conditioner to start frequently. 2. The resistance value of the indoor tube temperature sensor becomes smaller, causing the whole machine to be protected soon after startup 3. Indoor ambient temperature and tube temperature sensing performance changes, causing the air conditioner to work abnormally 4. The temperature change value of the indoor pipe is 0Q, which causes the whole machine to have no response when it is turned on by remote control. The air conditioner temperature sensor is broken and the solution: The sensor barrier of the temperature sensor occupies a relatively large proportion of the air conditioner faults. To make an accurate judgment, we must first understand its function. There are three temperature sensors in the air conditioner control part: 1. Room temperature sensor: It mainly detects the indoor temperature. When the indoor temperature reaches the set requirements, it controls the operation of the internal and external machines. The external machine stops during cooling and the internal machine continues to run. When heating, the internal machine stops after blowing off the residual heat. 2. Indoor tube temperature sensor: It mainly detects the coil temperature of the indoor evaporator, and plays the role of anti-cold wind, anti-overheating protection and automatic temperature control during heating. 3. Outdoor defrosting temperature sensor: It mainly detects the temperature of the outdoor condenser coil. When the outdoor coil temperature is lower than -6C for 2 minutes, the internal unit turns to the defrosting state. When the resistance of the outdoor coil sensor is too large , The indoor unit cannot work normally. Analysis of the reasons for the inconsistency between the displayed temperature of the air conditioner and the actual perceived temperature: 1. The remote control setting is incorrect; . The filter is not cleaned in time; 3. There are items at the air-conditioning inlet and outlet that affect the heating effect, and there is a heat source in the room or a large number of people in the room lead to a poor cooling effect; 4. Poor room insulation; 5. Too low indoor power supply voltage leads to low air conditioner working efficiency; 6. Too high or too low ambient temperature leads to poor effect. Precautions: In the air conditioner repair process, the temperature sensor (thermistor) has a high proportion of faults. Once there is an open circuit, short circuit or poor characteristic curve, the air conditioner will display an abnormal code and cannot work normally. As the temperature sensor is not marked with parameters and resistance values, it is often difficult to determine during maintenance. The resistance values of the same and different models are not necessarily the same. Temperature sensor, that is, when the temperature increases, the resistance decreases; when the temperature decreases, the resistance increases. The sampling voltage of the negative terminal of the CPU comparator is 1/2 of the CPU power supply voltage, which is 2.5V. The peripheral circuit RTI and RT2 op amp comparator positive terminal pull-up resistors, R1 and R2 are down bias resistors.

Product is shipped from China.
Alternative shipping methods can be selected at checkout.
Products are shipped by the individual Fruugo retailers, who are located across Europe and the rest of the world. The delivery times and shipping prices vary depending on the retailer's location, the destination country and the selected delivery method.
Fruugo offers two delivery options: Standard Delivery or Express Delivery. All retailers offer a standard delivery service, and some retailers also offer an express delivery service.
- Standard Delivery – Domestic Standard delivery takes approximately 2-5 business days from dispatch, while an International Standard delivery takes 5-14 business days from dispatch. Normally track and trace and proof of delivery are not available on a standard service.
- Express Delivery – Domestic Express delivery takes approximately 1-2 business days from dispatch, while an International Express delivery takes 3-7 business days from dispatch. Usually track and trace and/or proof of delivery are available on an express service.
Although Fruugo retailers endeavour to deliver within these timescales, please note that the above timescales are estimated and not guaranteed.
The delivery timescales do not include any customs clearing times beyond Fruugo's control.
Please allow additional shipping time for deliveries to exceptional locations that are hard to reach, and also during busy periods such as Christmas.
All carriers deliver during normal business working hours and may require a signature on receipt, so please ensure your order is delivered to an address where someone will be available to accept it.
We do our best to ensure that the products that you order are delivered to you in full and according to your specifications. However, should you receive an incomplete order, or items different from the ones you ordered, or there is some other reason why you are not satisfied with the order, you may return the order, or any products included in the order, and receive a full refund for the items.
Certain products purchased at Fruugo cannot be returned. They fall in the following categories:
- goods which are clearly personalised or made to your specifications
- goods which are liable to deteriorate rapidly, eg fresh fruit, fresh flowers
- sealed goods which are not suitable for return due to health protection or hygiene reasons, if opened, eg make up, underwear, pierced jewellery
- sealed audio or video recordings or computer software, if opened
- newspapers, periodicals and magazines
Please take reasonable care of the goods whilst in your care. Any goods returned must be in a resaleable condition. They must be unworn/unused with original tags attached and in original packaging. It is your responsibility to ensure that the goods are appropriately packaged to ensure they are not damaged in return transit.
