Honeywell HZ7040 shuts off after few minutes

My HZ7040 turns on and all functions work however after abuout a minute of operation, I hear a light click sound see inside a small spark when what looks like a bi-metalic strip with two points open up and the whole unit shuts off. The LCD screen goes blank. After a little bit, it will turn on again,(LCD works) and the cycle repeats - only working for a about a minute before shutting itself off.

Poor Quality Snap disc thermostats are the problem with many Honeywell products from day one. Since these are throw away products good luck in finding a replacement part.

This sounds like a theromostat problem. If you're NOT still under warranty you should at least open the heater and look for the theromostat. A lot of times you can buy replacement at a local electronic or hardware store and they're easy to replace. Good luck!

Dwayne, Try a new battery in remote, if that does not fix, replace your remote, replacements can be found at the larger hardware stores, eg. home depot, lowes,etc.

Thermostat not running furnace properly
Assuming that particular thermostat has a common mercury switch, the wiring behind or just inside the unit may be causing a strong enough magnetic field to throw off the balance of the mercury (liquid metal). The same scenario could be caused by other wiring or devices near the thermostat.
To test this theory, hold a compass as near as possible to the thermostat and wait it to come on automatically. If the needle moves when the switch engages, the magnetic field is strong enough the throw the balance off.


When tucking-in the wires for the thermostat, avoid winding the wires in a spiral or wrapping them around anything. An active current through wrapped or winding wires will create an electromagnetic field.

The heater comes on for a few seconds then shuts off but once or twice a week it comes on and operates like a normal heater
Mine does the same thing. I have a gas heater. It will fire up- run for less then a minute then shut off. then 2 minutes later does the same thing. I'm thinking of going with a differeny brand because this is using a lot of gas evertime it fires up just for a minute. if I turn it up it stays on till it reaches the temp then does that on off thing again. i think it is just the so called "feature" Honeywell is claiming to maintain the temp in our home, not realizing it is wasting your gas or electricity.

TV turns off after two minutes. Power light blinks for a few minutes then TV comes back on. Turning the power off after the set shuts itself off will cause the power light to blink five times for a minute...
5 blink indicates - AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.

My Honeywell rth230b thermostat continues to give me a flashing snowflake signal and will not allow the AC to turn on.
Your snowflake should flash for about five minutes, that is the time delay built into the thermostat. It should stop after that and your system should begin to function.

My honeywell heater was working one minute and not working the next.
HI I have this heater and no manual , and I was doing research on the internet and found that these haeters have an automatic shut off if it gets too hot and it wont come back on for a while until it is cooled down. I just unplug mine awhile or turn it off and then it comes back on when it cools down.

GE Portable Airconditioner - Model APN10AA Serial # GG509122
Ours was leaking water. After taking the covers off,cleaning it,and draining all the water out, I started getting the same problem with the light coming on every 7 minutes. I actually added some water to the system till it was too full and then drained it out through the plug. The light still came on every 7 minutes until I turned the unit off and then unplugged it for a few minutes. I plugged it back in, turned it on and reset the temperature. It seemed to reset itself and kept running normally. BB

2014 Micro Light by Flagstaff 19FD We have a Colman Mach roof ac unit, which is controlled on the unit. When we turn the knob to fan it blows great but when we turn it to cool low/high it runs for a few & then shuts off almost like it's bogging down. We can turn it off and turn it back on & it does it all over again.
