Can you replace the sensor without taking the whole unit apart? If not, and I was told you could not, then this seems useless.

you have to take the electrical cover off to access the sensor. Snip some wires and re-wire new sensor it should only take at most 20 minute to complete the task.

You do have to take the unit down as the hard wiring comes from behind the main unit. It isn't hard though. The hardest part is the unit dangling while you switch the wires out. If you can have someone hold the unit while you switch the wires it is easy. TURN POWER OFF, remove the unit, remove the wire nuts, undo the old sensor, connect the new sensor (reuse the wire nuts), and install whole unit back to house. It is cheaper to replace the sensor and not the hole unit.

The sensor assembly is not repairable only because the internal components can't be obtained. But the sensor as a complete assembly can be used as a direct replacement for a failed sensor assembly. Just shut off power to the entire unit, disconnect the wiring inside the dual lampholder that is connceted to the sensor assembly, unscrew the sensor assemblyand remove it then install the replacement sensor using a reverse of the removal procedure.

I agree w/ Gary because I did just that. It's cheaper and also the replacement sensor that I purchased thru Amazon, Heath / Zenith SL5316 is the best one I've had because you can adjust the range so the unit doesn't go off when vehicles go by. Also, unlike other units I've had, it doesn't keep going on & off when it's windy or raining

The 3 wires needed to replace the sensor are ready for installation--no need to take it apart. One needs only to remove the old sensor & note which wire is attached to which. Not a whole lot of brain power required for this task.

After reading the six responses, all are correct. Cut power, drop light fixture away from mounting box (1 or 2 screws), unscrew sensor from face plate, cut three wires, install new sensor, wire nut the 3 wires back to original connected wires (mine were red, black, white) reattach sensor to face plate and face plate to mounting box. Done.

It is an inexpensive sensor ... doubtful they make it in a way to be taken apart.

Gary is right. If by "whole unit" you mean a security lamp with attached sensor, then yes, you can replace a failed sensor with this one if you understand how to mount and wire it (easy). You can also install this (or the 5407) in a separate electrical box and use it to control a nice lantern instead of an ugly security lamp. Don't open this unit. If you live in California and have to comply with Title 24, the "dusk to dawn" feature does not comply; I used the 5407.

I don't know how to determine which sensor is bad. I had asked the technician at Belle Tire to look into it for me. They told me the far left hand part was bad so I took one off another vehicle and it fixed the problem right away. It only takes about 5 seconds to remove the part and replace it. Both the housing snap-in features and harness connectors are very easy to disengage and snap back together. The first part I ordered was defective. They sent a new one immediately... very responsive. Did not have to reset.

hello you will also need a tpms programmmer such as ts601 to replace the sensor

I belive they sell extension for the 02 sensor. I don't recommend splicing the wire. It might be possible at your own risk.

No. On the sensor. Will need. A. Pressure. Switch. And. I would need. Your. Model number. On the. Furance

It requires soldering - it's not a simple remove and replace. There are some YouTube videos out there, but unless you're very comfortable with soldering, suggest you buy a new unit.
1914561
Correct - just remove the old unit and replace with the new unit. Should take less than one minute...

I suppose you could go to the Manufacturers website. I have been told that they cannot be replaced and the wholeunit must be bought again. I hope that is not true. Seems to me you ought to be able to replace any part without having to buy a complete unit.

sorry for the delay. As I understand the sensor if you have a built in sensor you do not need this one

mmm in my case didn´t work because i bougth used and the battery was empty.. the trouble is the sensor hasn´t rechargable battery..you need to by a new one

Could be. Try pulling the power. Then, disconnect the sensor wires and the wired switch wires from the rear of the unit. Plug it back it. Does it do the same thing?

When I replaced my unit, which was cracked, all I did was remove & replace- my furnace has an external sensor. I think you would be fine doing the same thing.

You are better off replacing both and this kit will do it. I had the same issue in which I only needed one. But you are hard pressed to find just one sensor that will work. Save yourself the headache and use a kit.

I bought only the sensor. I'm on my second sensor now I got about a years use out of the first one.

No, I can't since I already did the replacement. It was simple, only took me 10 to 15 minutes, with simple tool (no special tool needed). It works great, as good as new.

The contact itself does not need to be programmed. If you are replacing a faulty sensor, you need to program your base unit accordingly. Every contact has its own unique ID, so you would need to find the faulty one and replace it with the ID if your new contact.

The end of the sensor is plastic and 0.75 x 1.25 x 2.5" long if you did could not disconnect the wires you would need a one and a half inch diameter hole. If you could cut the wires and put the sensor in and then reattach it you would just need a small hole.
