Comfort zone infrared heater runs for a few minutes a then completely shuts off


if unit runs ok for 3 to five minutes then completely shuts all power lamps off , then its hi temp limit sensor (safety) has been tripped , this usually goes out due to failure of main temp control , in point of fact contacts in temp switch literally weld them self's together and cant separate to allow heater to control temp

In new 3-alarm system just installed by electrician the alarms issue 3 long beeps and "FIRE" about every 10 minutes. Kidde is not available to help. Can you?


I think it could be one of three things.
The electrician may not have installed the back-up batteries.
The electrician may not have turned the primary power to the detector circuit on when he completed the work and now the battery is depleted.
The electrician may have tied the the detectors into a switched circuit which does not apply constant primary voltage.

Hopefully you can contact the installer to troubleshoot his work.

Why is the LED light completely off after the walk test and lockout time?


Yes, it works normally. Things have evolved in the technology of security systems and now it is standard to have any LED turned off on any motion detector (the LED's are now used for walk-testing only), the standard DSC and Honeywell wireless motions also do the same thing.

  • This is a normal function for your motion detector. It's also a great power saving function since most of the current draw on the batteries is when it's transmitting a detection signal so if you're home and moving around it will only transmit every few minutes instead of every second, saving on battery life significantly (up to 5 years on average) but after the 3-minute lockout the passive infrared scans continuously until it transmits another motion signal.
Reason: most burglaries are done by someone who has been there before, if they see the LED then they know the motion will catch them moving in that given spot, then they can "map-out" where it's safe to walk (where the LED doesn't light up) for when they plan to return for a robbery.

You can also make this device "more sensitive" by moving the jumper pin position by the right side battery and having the back mounting plate mounted using the bottom screw presets so it faces slightly downward instead of straight forward.

Helpful tip: Change the batteries every 4 years if you're using Alkaline (dead or not) since the detector was engineered "too energy efficient" and the batteries actually leak and corrode the interior PCB at about the 5-year point on about 15% of the detectors with factory original duracell batteries (from what I've experienced in field service).

Our hard wire smoke detector model i12060 just beeped really lound a few times and stopped, it glows green and flashes red every few minutes?


Change the 9V backup battery,with a new one.Push and hold the reset button for a minute or two for the alarm to to go off like about 30-40 sec. for the smoke detector to dectected the 9V backup battery power sourced.The green power LED light indicator will stop flashing also the beeping sounds too.

I am owner of HANNS.G HW191D 19" Monitor turn it self off completely out off power and dont want to boot up. But after about 20 - 40 minutes turn it self on for about 10 minutes. this happened all day any...


badcompanyx, Your unit is in need of warranty work or servicing by a qualified electronics technician. Possible bad "intermittant solder connection on "switch-mode-power-supply"/"CCFL inverter supply" and or BAD "faulty" electrolytic filter capacitors that need replacing. 12fixlouie

Small frigidaire with very small freezer completely fill with frost


Most of the smaller freezers are not self de-frosting, Im not certain about the one you have but usually the only way is to unplug them and let them thaw out for a few hours. Make sure to put towels down to absorb the water or you may have a mess.

Varifying detection


This happens often, as the units are basically very expensive bricks. They usually work quite fine for 12 months and 37 seconds though! The devices are built by prisoners in Ohio on a work-release program ... do you think they care? No, really, do ya? After getting hosed for $340, be prepared to cough up more cash. And, even then, there is no guarantee that the "repair" will last long, as it is only warranted for 6 months after the "repair" is completed. Oh, and btw, it WILL fail again. ZZTop watch  your speed, as the S2 you describe is doing squat. As for an onboard self-test feature, this is a GREAT idea, but, of course: 1) You are dreaming and 2) This would completely ruin Escort's business model.
