Composite verdict

Composite Safety Score: 71/100

One verdict blending 4 independently-sourced dimensions from two separate CPSC systems, each benchmarked against all 838 scored product categories by percentile rather than raw value, so no single huge-volume category can dominate the scale.

Dimension Value National percentile Weight applied Source
Injury severity (hospitalization + fatality blend) 23 94th 35% CPSC NEISS 20-year severity index

Methodology: each dimension is ranked against the full population's p10/p25/p50/p75/p90 breakpoints and interpolated to a 0-100 percentile; the composite is the weighted average of available percentiles. See methodology for the full benchmark table.

How this 47/100 score is built

The score is computed from four CPSC-derived factors for thermostats (for heating or cooling systems) - no opinion, no editorializing:

  • Injury volume 452 ER visits/yr Low volume
  • Severity (hospitalization rate) 22.6% Very high admission rate
  • Fatality rate 0.00% No recorded fatalities
  • 5-year trend+95%

What the CPSC Data Shows

Across the 20-year NEISS window from 2005 to 2024, injury counts for thermostats (for heating or cooling systems) are rising by about 95% over the last five years, with the busiest year on record being 2020 (898 estimated ER visits) and the quietest 2008 (186 estimated visits). The single most common ER diagnosis is laceration to the head, accounting for approximately 1,186 visits across the 20-year NEISS window, followed by internal injury to the head (1,136 cases). The 75+ age group absorbs the largest share of injuries, about 4,178 cases over the NEISS window, and females appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 22.6% of ER visits involving this product end in hospital admission or transfer.

Beyond the hospital-sampled NEISS projections, this page also aggregates 72 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how thermostats (for heating or cooling systems) fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

9/30/2019 · Incident, No Injury · HUNTER FAN COMPANY · Idaho

Hunter Fan Company thermostat model 4420. This thermostat caught fire Saturday afternoon and damaged the thermostat and wall surroundings. This problem could have burned the house down if I had not been right there at the time of ignition.

9/22/2015 · Unspecified · CADET MANUFACTURING CO. · Oregon

On the morning of 9/19/15 I turned on Cadet model C2002 thermostat to 64 degrees. 5 minutes later the smoke detector alarm went off, and we found the heater up in flames and starting to bubble the wall paint. Doused with water and fire extinguisher. Removed charred thermostat and removed another same model thermostat to find that it had what looked like the beginning of smoke marks (black soot) on top of the thermostat. Removed it and had all 11 of the Cadet thermostats replaced irregardless of model the next day. Cost $400.00

9/22/2011 · Incident, No Injury · HONEYWELL INTERNATIONAL HEADQUARTERS · Massachusetts

I sent the following to Honeywell regarding an incident with an electric baseboard thermostat. The email was sent to the attention of [REDACTED] at ecc@honeywell.com **************************** After reading that some of your line level thermostats were being recalled, I contacted the recall hotline regarding a CT62B1015 that overheated on me. The recall hotline told me that this model was not on the recall list, and they referred me to customer service, who acknowledged that there were reported problems with this thermostat and referred me to you. One of the inside contacts (red wire,lower contact) is badly charred, the gray housing is also melted and charred and the wire insulation is melted. Fortunately, we smelled the overheated plastic and turned off the power immediately. I believe the problem is in the design or the manufacturing. The thermostat was installed by a licensed electrician. I have replaced the unit with another type of line level thermostat – a Cadet TH110-DP-P, which I believe is also made by Honeywell. My reason for contacting you is to record the problem with my original thermostat. This model may need to be added to the recall list. Please let me know if there is any more information I can provide and if this model will be added to the recall list. Sincerely, [REDACTED]

Alkaline batteries in the blue back-lit touch panel thermostat leaked, causing the thermostat to fail, brief electrical burning smell, AC switched to heat mode- despite outside temperature being in the 80's. Had to shut off power to entire HVAC system to stop, now don't have AC.

8/21/2011 · Incident, No Injury · QUAD SIX, INC. (HONEYWELL, INC.) · Connecticut

In 2007 I bought two Honeywell RLV430 Thermostats which were installed by a licensed electrician. In the past weeks I noticed a grey discoloration on my paint on the wall - like smoke from a candle flame. This happened with two thermostats of this kind - one in my living room and one in my bedroom. I called another licensed electrician to look at it as I was concerned about it. The electrician stated that the two thermostats were installed correctly and that nothing was wrong with my electrical lines. They were also in line with what was required for my heaters. He advised to remove them as the "signs of smoke: were not only on my walls, but also inside the thermostats. I had him remove both and will have them replaced. I am worried that there might be something wrong with these thermostats and will email the company as well. OI have photos of my walls and will put one thermostat at the disposal of Honeywell should they wish to evaluate the unit. I am writing as I am not sure if others have reported the same issues.

8/13/2018 · Incident, No Injury · HONEYWELL INTERNATIONAL HEADQUARTERS · New York

We purchased a Honeywell RLV3120 Non-Programmable Thermostat and had it installed by an electrician in September of 2014. While it was in use for residential heating during cold weather I noticed that the top of the thermostat would produce a lot of heat. We had 2 new electricians check to make sure that it was installed properly and they found no problems. During the heating season of 2017 we were away on vacation and received a text message with a photo of the thermostat from a friend who was monitoring our home. The photo showed a large black burn mark on the sheetrock above the thermostat, exactly where I had always felt the worrisome hot spot. The thermostat was immediately disconnected and replaced.

8/1/2012 · Incident, No Injury · HONEYWELL INTERNATIONAL HEADQUARTERS · Connecticut

I noticed that there were scorch marks above 3 of my 6 Honeywell RLV430 thermostats. I had a licensed electrician come look at the the wiring, thinking that it was the wiring in the wall that was causing the scorch marks. He said there was nothing wrong with the wiring, it was the thermostat unit, possibly a battery within the unit going bad. I now have the breakers to all the units shut off.
