Lost operating manual. is the temperature light supposed to blink when unit is operating

If the operation light is blinking, it means there is an error with the unit. The number of blinks can indicate what the error is.
Here are some common error codes for Toshiba air conditioning units:

• Blinking once: Indoor unit room temperature sensor error
• Blinking twice: Indoor unit coil outlet temperature sensor error
• Blinking three times: Indoor unit coil inlet temperature sensor error
• Blinking four times: Outdoor unit discharge temperature sensor error
• Blinking five times: Outdoor unit suction temperature sensor error
• Blinking six times: Indoor unit EEPROM error
• Blinking seven times: Outdoor unit EEPROM error
• Blinking eight times: Indoor unit remote control error

If you can determine the number of blinks, you can refer to the user manual to see what the error code means and what steps you can take to fix it. If you don't have the manual, you may be able to find it online or contact Toshiba customer support for assistance.

Hi,

there might be a filter that needs to be changed or the machine needs service. Please check the troubleshooting section of your product manual to determine the specific meaning of the blinking light and the auto-off that's occurring. If you don't have the manual, then please call Fujitsu and request a copy be emailed to you. If that fails, you might need to take your product into a place like Geeksquad/Bestbuy for servicing.

Thank you.

Not sure what your model number but following is for H-6003.

OPERATING INSTRUCTIONS:
•
Plug the power cord into a wall outlet
(110-120V AC, 60Hz)
•
This heater has only one (1) power setting, pressing the
rocker switch to the ON position, it will give you 700 watts
of heat. When you want to switch off, then just press
the switch to the OFF position.
•
When the unit is turned on the power indicator light will
illuminate to tell you that the heater is functioning.
THERMOSTAT INSTRUCTIONS:
•
Before setting the thermostat, allow the heater to operate
and warm up the room. You need to set the thermostat
on MAX to start the heater.
•
When the desired temperature/comfort level is reached,
lower the thermostat setting until the heater stops
operating.
•
The control will now automatically maintain the pre-set
temperature level by turning the heater ON and OFF

Does that smoker have a "high limit" snap switch inside? If it does, that's the likely cause - try replacing it with a correctly-rated one.

Hi,
Could this be the one?

If not,please let me know your models name and number through the [Fixya] comments option.If yes please rate the answer.

Thanks!

I had a chat session with Phillips technical support for you and they knew nothing. However, this is a dedicated tech support unit for this monitor. This is what they gave me:

You may contact at 1-866-310-0787 and a representative with expertise in handling this unit will be glad to assist you. Hours of operation are Monday - Saturday 12.00 PM - 9.00 PM EST

As a tech expert, I would suppose those 7 blinks mean something very specific. You just need them to tell you what it is. It's located in a service manual, that neither you nor I have access to.

The LO/Filter light blinking is an indication of Flame Failure . It means the unit had a flame and then lost the flame signal to the PCB . Have the incoming gas supply checked for proper operating range . Also have the flame rod /burner areas checked for debris/sooting/dirty flame rod/ etc...Spiders have a way of getting inside the burner areas and misdirecting the gas flow in the burners . This is common on units that have been sitting dormant for long periods .
The 68/Filter/On lights blinking are an indication of an "overheating " situation . Inspect the overall unit inside the cabinet for any dirty issues(pet hair/dust/dirt/gasket integrity/etc...) .
These procedures should be done by a qualified service technician due to liabilities involving gas fired products !

I fixed this problem by disassembling the panels. On the front then sides then back of the unit. The first thing I noticed was some debris in the exhaust fan wheel on the back side. I used some long wood skewer to fish out the debris and even shook the unit upside down. (It's very heavy and would recommend help with shaking the unit.) Also, I think i found a little sensor that is about the size of a thumb drive and incased in a transparent plastic box. I tapped it with my finger and noticed this little black thing bounce up and down inside under the green circuit board. its located right above the drain connection. I didn't do anything else with this. I assumed its the sensor to measure the water buildup. I also found a small toy in the front fan wheel that blows the cool air through the top of the unit. fell out during the shake down. The final thing I noticed was when re-assembling the unit. On the front side you will see the two metal radiator looking panels. Between the two panels is a wire sensor that looks like a temperature measuring device. I had noticed it was touching the metal part of the radiator panel so I gently streightened it out so that it was parallel with the panels and not touching. I pressed the power button and it hasn't shut of yet. I snapped the front panel back on and all is good.
I have the white upright sharp AC unit with the three lights in the front and a power button next to the IR sensor. I lost the remote control and couldn't figured out why the unit would start up then shut down after a minute of use. The operation light would blink red then the orange timer light would blink next. Then both lights would blink simultaneously, then repeat. I thought this was a timer setting. but the unit is supposed to reset after disconnected from the power.

Press the *power button* once to start the heater on high power, continuous run. If left at this setting, the unit will run continuously on high power (1500 watts, 12.5 amps) and will not shut off until the unit is manually turned off.
Press the *power button* again, to change to low power, continuous run, (900 watts, 7.5 amps) and will not shut off until the unit is manually turned off.

Set temperature:

Press the temp/timer button until the temperature icon blinks. Use the up and down arrows to set the desired temperature.
The temperature icon will stop blinking and the current room temperature will reappear after the desired temperature is set.

The heater will turn off and on to achieve the desired temperature.

Set timer: (auto off)

Press the timer/timer button until the timer icon blinks. The hour display will appear. The auto off icon will also appear.
Use the up and down arrow buttons to set the heater operation time between 1 and 10 hours. This function will activate once the timer icon stops blinking. The heater will automatically turn off whn the times runs out.

Set timer: (auto on)

Press the temp/timer button until the timer icon blinks. The hour display will appear. The auto on icon will also appear.
Use the up and down arrow buttons to set the heater start time between 1 and 10 hours. This function will activate once the timer icon stops blinking.
The heater will automatically turn on when time expires.

Hope this helps!
